      Summary
      • Abstract We first propose fundamental solutions of wave propagation in dispersive chain subject to a localized initial perturbation in the displacement. Analytical solutions are obtained for both second order nonlinear dispersive chain and homogenous harmonic chain using stationary phase approximation. Solution is also compared with numerical results from molecular dynamics (MD) simulations. Locally dominant phonon modes (k-space) are introduced based on these solutions. These locally defined spatially and temporally varying phonon modes k(x, t) are critical to the concept of the local thermodynamic equilibrium (LTE). Wave propagation accompanying with the nonequilibrium dynamics leads to the excitation of these locally defined phonon modes. It is found that the system energy is gradually redistributed among these excited phonons modes (k-space). This redistribution process is only possible with nonlinear dispersion and requires a finite amount of time to achieve a steady state distribution. This time scale is dependent on the spatial distribution (or frequency content) of the initial perturbation and the dispersion relation. Sharper and more concentrated perturbation leads to a faster energy redistribution and dissipation. This energy redistribution generates localized phonons with various frequencies that can be important for phonon-phonon interaction and energy dissipation in nonlinear systems. Depending on the initial perturbation and temperature, the time scale associated with this energy distribution can be critical for energy dissipation compared to the Umklapp scattering process. Ballistic type of heat transport along the harmonic chain reveals that at any given position, the lowest mode (k = 0) is excited first and gradually expanding to the highest mode (kmax(x,t)), where kmax(x,t) can only asymptotically approach the maximum mode kB of the first Brillouin zone (kmax(x,t) → kB). No energy distributed into modes with kmax(x,t) < k < kB demonstrates that the local thermodynamic equilibrium cannot be established in harmonic chain. Energy is shown to be uniformly distributed in all available phonon modes k ≤ kmax(x,t) at any position with heat transfer along the harmonic chain. The energy flux along the chain is shown to be a constant with time and proportional to the sound speed (ballistic transport). Comparison with the Fourier' law leads to a time-dependent thermal conductivity that diverges with time.

      Summary
      • Abstract: Inelastic X-ray scattering (IXS) experiments were carried out at room temperature at BL35XU of the SPring-8 on a single crystal Mg85 Zn6 Y9 alloy with a synchronized long-period stacking ordered (LPSO) phase of purely 18R type. The IXS measurements were carried out in both the longitudinal and transverse directions along the Γ -K and Γ -M (momentum vector q ⊥ lattice axis c ), and Γ -A ( q ∥ c ) directions for the energy transfers ω below 40 meV. Peaks arising from longitudinal and transverse acoustic (LA and TA) modes were clearly observed in the IXS spectra. The dispersion relations of the LA and TA modes in the Mg85 Zn6 Y9 LPSO alloy are mostly similar to those of previous INS data on single crystal pure Mg. New impurity-derived dispersion-less excitation modes are observed along all of the crystal directions at about 5, 10, and 17 meV. Partial vibrational density of states (vDOS) was obtained using an a b i n i t i o molecular dynamics simulation, and it was found that the ∼ 10 meV peak mainly originates from the phonon excitations inside the L12 -type Zn6 Y8 clusters and the ∼ 17 meV peak from those between the cluster and the host Mg atoms, and a small shoulder at 5 meV consists of motions of all the elements. These findings clarify that the dispersion-less modes mainly correspond to localized stretching and twisting modes around the impurity clusters in the LPSO alloys. Graphical abstract:

      Summary
      • Abstract The influence of the elastic anisotropy on the thermal conductivity in silicon nanofilms and nanowires for the diffuse scattering of phonons at boundaries at low temperatures has been investigated. It is shown that for the correct description of the phonon transport in silicon nanofilms, in contrast to isotropic medium, it is necessary to introduce two orientation parameters, which take into account the dependencies of the kinetic characteristics of phonon system on the direction of heat flow and the orientation of the film plane with respect to the crystal axes. The optimum orientations of the silicon film plane and directions of heat flow, which provide maximum or minimum heat transfer from elements of the silicon microcircuits have been determined. It is shown that for the nanowires with a square cross‐section the values of thermal conductivity depend mainly on the direction of heat flow. However, in rather wide silicon nanofilms they are mainly determined by the orientation of the film plane with respect to the crystal axes. The dependencies of the thermal conductivity and the mean free paths of the phonons in the boundary scattering regime on the geometric parameters of nanostructures have been analyzed.

      Summary
      • AbstractWe present a theoretical study on the pure dephasing process of colloidal semiconductor quantum dots induced by lattice vibrations using continuum model calculations. By solving the time dependent Liouville-von Neumann equation, we present the ultrafast Rabi oscillations between excitonic state and virtual state via exciton-phonon interaction and obtain the pure dephasing time from the fast decayed envelope of the Rabi oscillations. The interaction between exciton and longitudinal optical phonon vibration is found to dominate the pure dephasing process and the dephasing time increases nonlinearly with the reduction of exciton-phonon coupling strength. We further find that the pure dephasing time of large quantum dots is more sensitive to temperature than small quantum dots.Highlights<list-item>•Pure dephasing time of spherical semiconductor quantum dot is calculated.</list-item><list-item>•Optical phonon mode dominates the pure dephasing process.</list-item><list-item>•Pure dephasing time nonlinearly increases with decreasing phonon coupling.</list-item><list-item>•Pure dephasing time of large quantum dots is more sensitive on temperature.</list-item>

      Summary
      • Abstract Si1‐xGex nanocrystals (NCs) of different composition and size were generated using the Molecular Dynamics (MD) method by minimizing NC&apos;s total energy calculated using Tersoff&apos;s empirical potential and applying rigid boundary conditions. The dynamical matrix of the relaxed NC was constructed and the NC phonon modes were calculated. The localisation of the principal (Si‐Si, Si‐Ge and Ge‐Ge) modes is investigated by analysing their inverse participation ratio. The dependence of the corresponding Raman spectra, obtained by employing the bond polarisability model, upon x and the NC size is presented and compared to previous calculated results and available experimental data.

      Summary
      • AbstractThe creation of stacking fault in Al4SiC4crystal structure due to a phonon mode (E1, 139.7 cm−1, Raman active) atΓ-point with negative mode-Grüneisen constant (−0.28). (a) 3-D side-view; (b) 2-D side view.AbstractThe phonon spectra, chemical bonding, thermal and thermodynamic properties of Al4SiC4and Al4Si2C5are calculated by first-principles using density functional theory. Raman and infrared (IR) active phonon modes and their eigenvectors are analyzed. Phonon mode-Grünseisen parameter and macroscopic Grünseisen constants are evaluated from phonon spectra. Employing quasiharmonic approximation (QHA), the thermal expansion tensor is obtained. The calculated volumetric thermal expansion coefficient (TEC) of Al4SiC4is high than that of Al4Si2C5; and the linear TEC in the [001] direction is slightly higher than that of the [100] direction for both compounds. The computed average linear TECs for Al4SiC4and Al4Si2C5are 9.96 × 10−6K−1and 8.9 × 10−6K−1in a range from room temperature to 1500 K, respectively. Other thermal properties such as specific heats (CV, andCP), entropy (S), isothermal and isobaric bulk moduli (KTandKS) are also discussed. Using Slack's model, it is found that thermal conductivities are 59.9 W m−1K−1and 78.3 W m−1K−1at room temperature for Al4SiC4and Al4Si2C5, respectively. The response of chemical bonds to hydrostatic pressure is discussed using Milliken population analysis. We also plot the charge density and its reduced density gradient to reveal the covalent bonds in the structure.

      Summary
      • The first two volumes in this series published twenty years ago contained chapters devoted to anharmonic properties of solids, ab initio calculations of phonons in metals and insulators, and surface phonons. In the intervening years each of these important areas of lattice dynamics has undergone significant developments. This volume is therefore concerned with reviewing the current status of these areas.Chapter one deals with the path-integral quantum Monte-Carlo method as a numerical simulation approach and looks at how this has been applied successfully to the determination of low temperature thermodynamic properties of anharmonic crystals and to certain dynamical properties as well. Chapter two is concerned with the calculation of static and dynamic properties of anharmonic crystals in the quantum regime. Chapter three discusses intrinsic anharmonic localized modes that have been intensively studied recently. Two topics, ab initio calculations of phonons in metals, and surface phonons are dealt with in the next chapter. The remaining two chapters are devoted to topics that have not been treated in previous volumes. One is phonon transport and the second is phonons in disordered crystals.The work described in the six chapters of this volume testifies to the continuing vitality of the field of dynamical properties of solids nearly a century after its founding.

      Summary
      • Abstract : Mid‐infrared hyperbolic phonon polaritons are demonstrated on a van der Waals semiconducting layered oxide, α ‐MoO3, as described in article number1705318 by Weiguang Xie, Huanjun Chen, Shaozhi Deng, Ningsheng Xu, and co‐workers. By using a real‐space near‐field optical nanoimaging technique, the phonon polaritons are shown to exhibit ultrahigh electromagnetic‐field confinement, as well as low damping rates, which can be tuned upon metal‐ion intercalation.

      Phonon properties in different types of single-walled carbon nanotube thin films probed by Raman spectroscopy.

      Summary
      • AbstractWe report a temperature-dependent (70–450 K) Raman study of single-walled carbon nanotube (CNT) thin films as a function of their thickness and the conductivity type of the nanotubes used to fabricate these films. The CNT films Raman G mode positions and widths exhibit two apparent regimes, a nonlinear temperature dependence at low temperatures (<270 K), which is explained by the phenomenon of optical phonon decay, and a linear temperature dependence above 270 K. The first-order temperature coefficient, determined for the linear regime, depends on the film thickness and type of CNTs, changed up to 20%. In addition, we observed another factor causing phonon shifts that is not related to the temperature but strongly depend on the film thickness and conductivity type of the CNTs. Finally, we ascertained the local temperature changes of the film samples upon laser heating as a function of the global temperature, demonstrating significant differences in the heating process, suggesting that heat evacuation efficiency depends type of the film, its thickness and global temperature. These results contribute to the understanding of the thermal properties and heat dissipation in CNT films, which are crucial for use in a variety of future applications.

      Summary
      • ABSTRACTThe cooling dynamics of hot charge carriers in colloidal lead chalcogenide nanocrystals is studied by white light transient absorption spectroscopy. We demonstrate a transient accumulation of charge carriers at a high-energy critical point in the Brillouin zone. Using a theoretical study of the cooling rate in lead chalcogenides, we attribute this slowing down of charge carrier cooling to a phonon scattering bottleneck around this critical point. Our approach allows for the first ever determination of hot carrier cooling rates, relevant ine.g.modeling of multiple exciton generation.

      Summary
      • AbstractReducing lattice thermal conductivity (κl) of a thermoelectric material is one of the most popular strategies to improve its thermoelectric performance. Particularly, many efforts have been focused on decreasing grain size to effectively scatter low‐frequency phonons by boundary scattering. In addition to the boundary scattering, we have recently demonstrated that dense arrays of dislocations formed in grain boundaries can further reduce theκlby dislocation scattering at room temperature and above. In order to closely examine the effect of the dislocation scattering, theκlof polycrystalline Bi0.5Sb1.5Te3samples with and without dislocations were measured at low temperature (T < 200 K). Because other phonon scattering mechanisms like Umklapp and point‐defect scatterings are not dominant at low temperature, we clearly show the presence of the dislocation scattering in the sample with the dislocations by successfully describing its low temperature experimentalκlwith a theoretical model.

      Summary
      • AbstractTwins, as one kind of crystal defects, are often been observed in various material systems. However, its effect on phonon scattering is much less investigated comparing to other defects. The difficulty in understanding the phonon scattering effect by twins lies in the inevitable presence of other defects (e.g., grain boundaries), which overshadow the intrinsic scattering effect by twins. In order to resolve the issue, three different kinds of InSb specimens with microscale grains, nanoscale grains, and nanoscale grains with nanotwins were prepared in this work. By comparing the thermal conductivities between different specimens, our results unambiguously show that phonons can indeed be scattered by twin boundaries. However, in a striking contrast to grain boundaries, phonon scattering effect by twin boundaries is noticeably weaker, which could be ascribed to the coherent characteristics of twin boundaries.Graphical abstractHighlights<list-item>•Phonon scattering effect by twin boundaries was experimentally investigated.</list-item><list-item>•Comparison of phonon scattering effects between twin boundaries and grain boundaries was made.</list-item><list-item>•Noticeably weaker phonon scattering effect by twin boundaries should be ascribed to its coherence.</list-item>

      Phonon scattering during dislocation motion inducing stress-drop in cubic metals.

      Summary
      • AbstractThis work proves that scattering of elastic waves in the dislocation core induces an unusual behavior calledstress-drop, which is defined for the first time in this study as a phenomenon where an externally applied stress drops inside a nano-sized cubic metal during dislocation motion. We develop a theoretical phonon scattering model based on discrete lattice dynamics and derive simple analytical equations to quantify the magnitude of the stress-drop. The proposed model is supported by atomistic simulations of perfect dislocations in bcc iron, where the stress-drop resulting from bond breaking is inversely proportional to the square of the dislocation speed. The derived equation is in excellent agreement with direct atomistic simulations for edge and screw dislocations. Next, we extend the equation to the edge dislocation in fcc aluminum where the dislocation exists as a stacking fault ribbon surrounded by two Shockley partial dislocations and thus the interaction between them is important. The extended equation accurately predicts the phonon scattering, resulting in the stress-drop by the oscillation of the two partials as well as bond breaking. In addition to the discussion on the validity of our model and equations at absolute zero, we investigate the temperature and size effects on our equations. As temperature increases, the magnitude of the stress-drop decreases and converges to zero even at very low temperature because of the extremely small Peierls barrier. Moreover, the magnitude of the stress-drop decreases, as the thickness of the nanoplate increases, which shows that the stress-drop is a mechanical behavior that is prominent on the nanoscale.Graphical abstract

      Summary
      • AbstractPhonon dispersion ω(q) and phonon density of states g(ω) of the high‐pressure rocksalt phase of InN are calculated ab initio, at different pressures, using the density functional perturbation theory. Born effective charge eT*, LDA values of dielectric constant ε∞ and of the electronic gap Eg are obtained as well. Building on the theoretical knowledge of phonon frequencies and their evolution with pressure, we attempt to interpret the set of six bands found previously in Raman spectra of epitaxial layers and of InN‐nanowires.

      Summary
      • AbstractThree potentials of the Finnis–Sinclair type are studied with regard to their suitability for predicting bulk thermal and elastic properties of fcc metals Cu, Ag, Au and Pt over a wide temperature range. We start with a particular parametrization of the Finnis–Sinclair model known as the Sutton–Chen potential and a later version of the same, known as the quantum Sutton–Chen potential. The quasiharmonic lattice dynamics method is used to study the temperature variation of the thermodynamic properties. Both models are found to yield poor results for thermal expansion, which can be traced to rapid softening of transverse phonon frequencies with increasing lattice parameter. The form of the Sutton–Chen potential is modified here to seek improvement in the agreement between quasiharmonic calculations and experimental data. It is found that the modified potential better predicts bulk properties in nearly all cases studied. Significant improvement is seen over the Sutton–Chen potential, while lesser but still substantial improvement is observed over the Quantum-Sutton Chen potential.AbstractHighlights<list-item>•We study temperature-dependence of thermodynamic properties of fcc metals.</list-item><list-item>•We compare results for Sutton–Chen (SC) and Quantum Sutton–Chen potentials.</list-item><list-item>•We propose modification of SC potential to improve agreement with experiments.</list-item>

      Summary
      • Abstract : Hybrid density functional theory calculations are performed for the first time on the phonon dispersion and thermodynamic properties of WS2 ‐based single‐wall nanotubes. Symmetry analysis is presented for phonon modes in nanotubes using the standard (crystallographic) factorization for line groups. Symmetry and the number of infra‐red and Raman active modes in achiral WS2 nanotubes are given for armchair and zigzag chiralities. It is demonstrated that a number of infrared and Raman active modes is independent on the nanotube diameter. The zone‐folding approach is applied to find out an impact of curvature on electron and phonon band structure of nanotubes rolled up from the monolayer. Phonon frequencies obtained both for layers and nanotubes are used to compute the thermal contributions to their thermodynamic functions. The temperature dependences of energy, entropy, and heat capacity of nanotubes are estimated with respect to those of the monolayer. The role of phonons in the stability estimation of nanotubes is discussed based on Helmholtz free energy calculations. © 2017 Wiley Periodicals, Inc. Abstract : Because of many useful properties, the stability, electron, and phonon structure of bulk WS2, its monolayer, and nanotubes was a subject of extensive experimental and theoretical investigations. In this work, we perform the first‐principles study of the electron and phonon band structure and thermodynamic properties of WS2 nanotubes. Temperature dependences of energy, entropy, and heat capacity of nanotubes are estimated.

      Phonon states of B12P2 crystals: Ab initio calculation and experiment.

      Notes
      • In: Journal of physics and chemistry of solids, Vol. 110, no. ( 2017), p.248-253.
      Summary
      • AbstractUsing methods of density functional theory (DFT) and Raman spectroscopy (RS) we investigate the phonon structure of the B12P2crystal. The theory is consistent with the experiment for all twelve Raman-active modes. We have calculated Born charges, oscillator strengths, longitudinal-transverse splitting, and dielectric functions of dipole modes. The results are used to interpret the known IR spectra of B12P2. Analysis of phonon dispersion shows that the crystal is dynamically stable. The energy gap separating acoustic and optical phonons is absent due to the overlap of the phonon states at the Brillouin zone boundary. Vibrations of phosphorus and boron atoms contribute to the low- and high-frequency regions of the phonon density of states, respectively.

      Summary
      • AbstractRecently, there has been increasing interest in phonon thermal transport in low-dimensional materials, due to the crucial importance of dissipating and managing heat in micro- and nano-electronic devices. Significant progress has been achieved for one-dimensional (1D) systems, both theoretically and experimentally. However, the study of heat conduction in two-dimensional (2D) systems is still in its infancy due to the limited availability of 2D materials and the technical challenges of fabricating suspended samples that are suitable for thermal measurements. In this review, we outline different experimental techniques and theoretical approaches for phonon thermal transport in 2D materials, discuss the problems and challenges of phonon thermal transport measurements and provide a comparison between existing experimental data. Special attention will be given to the effects of size, dimensionality, anisotropy and mode contributions in novel 2D systems, including graphene, boron nitride, MoS2, black phosphorous and silicene.

      Summary
      • Abstract: Silicon carbide (SiC) is a wide band gap semiconductor with a variety of industrial applications. Among its many useful properties is its high thermal conductivity, which makes it advantageous for thermal management applications. In this paper we present ab initio calculations of the in-plane and cross-plane thermal conductivities, κ in and κ out, of three common hexagonal polytypes of SiC: 2H, 4H and 6H. The phonon Boltzmann transport equation is solved iteratively using as input interatomic force constants determined from density functional theory. Both κ in and κ out decrease with increasing n in n H SiC because of additional low-lying optic phonon branches. These optic branches are characterized by low phonon group velocities, and they increase the phase space for phonon-phonon scattering of acoustic modes. Also, for all n, κ in is found to be larger than κ out in the temperature range considered. At electron concentrations present in experimental samples, scattering of phonons by electrons is shown to be negligible except well below room temperature where it can lead to a significant reduction of the lattice thermal conductivity. This work highlights the power of ab initio approaches in giving quantitative, predictive descriptions of thermal transport in materials. It helps explain the qualitative disagreement that exists among different sets of measured thermal conductivity data and provides information of the relative quality of samples from which measured data was obtained. Highlights: Ab initio calculation of the lattice thermal conductivity, k, is carried out on the hexagonal 2H, 4H and 6H SiC. Trends in the in- and cross-plane ks are determined and it is found that k(2H) > k(4H) > k(6H) for a given temperature. Comparison of k with available experimental data is made. Phonon-electron scattering is found to reduce k negligibly at room temperature but significantly at lower temperatures.

Abstract : Combining the best of different monolayers in one ultimate van der Waals (vdW) heterostructure is an appealing approach for practical applications. Recently, a graphene (GR) and molybdenum diselenide (MoSe2 ) heterobilayer was successfully fabricated experimentally. The superior electrical conductivity of GR combined with the unique photoelectrical properties and direct bandgap of MoSe2 can yield many potential applications, such as Li-ion batteries, tunneling field effect transistors and two-dimensional non-volatile memory devices. Efficient heat conduction within the device components is of great importance for nanoelectronic performance. In this work, the cross-plane interfacial thermal resistance ( R ) and in-plane thermal conductivity ( κ ) of the GR/MoSe2 vdW heterobilayer are systematically investigated using classical molecular dynamics (MD) simulations. The predicted R at a temperature of 300 K is equal to 1.91 × 10 −7 K m 2 W −1 . Effects of several modulators such as temperature, contact pressure and vacancy defects are evaluated, which are all found to have negative correlations with the calculated interfacial thermal resistance. The highest reduction of R amounts to 75% for doubled coupling strength between GR and MoSe2 . Spectral energy density (SED) and phonon density of states (Ph-DOS) analyses are performed to gain further insights into the phonon properties of GR and MoSe2 . Our study provides reasonable guidelines to increase heat dissipation efficiency for future GR/MoSe2 based applications.

      Summary
      • ABSTRACT: The thermal conductance of isotopic-superlattice graphene nanoribbons randomly mixed with isotope defects is investigated by atomistic Green's function method. The isotopic-superlattice structure reduces the thermal conductance, which changes non-monotonically as the superlattice period length decreases, and there exists a minimum thermal conductance at the critical period length. About 20% defects just further increase the reduction and shorten the critical period length. As the defect concentration in superlattice increases, the thermal conductance decreases monotonically in the zigzag nanoribbon, but in armchair nanoribbon the thermal conductance first decreases to its minimum value and then increases. The isotopic doping effect is particularly evident for large isotope mass, in armchair nanoribbons and for out-of-plane phonon modes. Isotope defects lead to additional phonon scattering in the superlattice structure, which is explained by analyzing the phonon transmittance.

      Summary
      • Abstracth-BN/graphene/h-BN sandwiched systems exhibit distinct stacking-dependent phonon transport features. We provide a new analysis method to understand the physical mechanism of phonon–phonon coupling and the phonon modes’ contributions to the thermal boundary conductance at SLG/h-BN interfaces.AbstractHexagonal boron nitride (h-BN) is a promising substrate for graphene based nano-electronic devices. We investigate the ballistic phonon transport at the interface of vertically stacked graphene and h-BN heterostructures using first principles density functional theory and atomistic Green's function simulations considering the influence of lattice stacking. We compute the frequency and wave-vector dependent transmission function and observe distinct stacking-dependent phonon transmission features for the h-BN/graphene/h-BN sandwiched systems. We find that the in-plane acoustic modes have the dominant contributions to the phonon transmission and thermal boundary conductance (TBC) for the interfaces with the carbon atom located directly on top of the boron atom (C–B matched) because of low interfacial spacing. The low interfacial spacing is a consequence of the differences in the effective atomic volume of N and B and the difference in the local electron density around N and B. For the structures with the carbon atom directly on top of the nitrogen atom (C–N matched), the spatial distance increases and the contribution of in-plane modes to the TBC decreases leading to higher contributions by out-of-plane acoustic modes. We find that the C–B matched interfaces have stronger phonon–phonon coupling than the C–N matched interfaces, which results in significantly higher TBC (more than 50%) in the C–B matched interface. The findings in this study will provide insights to understand the mechanism of phonon transport at h-BN/graphene/h-BN interfaces, to better explain the experimental observations and to engineer these interfaces to enhance heat dissipation in graphene based electronic devices.

      Summary
      • Highlights: Electron temperature follows almost spatial distribution of laser pulse intensity. Electron temperature decays sharply as distance from the film edge increases along. Lattice site temperature rises and decays gradually inside thin film. Electron-phonon coupling factor results in gradual transfer of electron excess energy to lattice site. Abstract: Laser short-pulse heating of a curved aluminum thin film is investigated. The Boltzmann transport equation is incorporated to formulate the heating situation. A Gaussian laser intensity distribution is considered along the film arc and time exponentially decaying of pulse intensity is incorporated in the analysis. The governing equations of energy transport in the electron and lattice sub-systems are coupled through the electron-phonon coupling parameter. To quantify the phonon intensity distribution in the thin film, equivalent equilibrium temperature is introduced, which is associated with the average energy of all phonons around a local point when the phonon energies are redistributed adiabatically to an equilibrium state. It is found the numerical simulations that electron temperature follows similar trend to the spatial distribution of the laser pulse intensity at the film edge. Temporal variation of electron temperature does not follow the laser pulse intensity distribution. The rise of temperature in the electron sub-system is fast while it remains slow in the lattice sub-system.

      Summary
      • ABSTRACTPhonon transport inside a curved film is considered and phonon intensity distribution is instigated for various film arc angles and film radii. A thermal disturbance is applied at the edges of the curved film and resulting phonon transport characteristics are simulated by incorporating the radiative phonon transport equation, which is derived for the general coordinate system to fit any film geometry. Equivalent equilibrium temperature is introduced to quantify the phonon intensity distribution inside the film. In the analysis, the total area and the thickness of the film are kept constant for various film arc angles and radii. It is found that equivalent equilibrium temperature decay is sharp in the close region of the high temperature edge inside the curved film. Normalized equivalent equilibrium temperature reduces with increasing arc angle; however, this decrease is not considerable, i.e., it is in order of 4%. Similar arguments are applied for the temperature distribution along the film thickness in the radial direction.

      Summary
      • Abstract : The transport properties of phonons in a nanocomposite have been investigated in this paper. In our model, the nanocomposite consists of nanoparticles embedded in a host dielectric material. The phonon dispersion relation of the nanocomposite is characterized in terms of a defined phonon refractive index and a filling factor parameter. This phonon refractive index depends on its velocity whereas the filling factor is determined by the diameter of the nanoparticles. Consequently, at zero filling, only the host material is present. Our model calculations also include point defects such as impurities, vacancies and the mass and size variations of nanoparticles. The phonon conductivity is determined by employing the Kubo formulism. We also report our calculated results for the phonon relaxation rates due to point defects and boundaries scattering where the latter is due to phonons interacting with the surface boundaries of nanoparticles and the host material. The thermal conductivity, dispersion relation, velocity, density‐of‐states and relaxation rates of phonons are determined by the filling factor and phonon refractive indices of the nanoparticles. There is a good agreement between our numerical results and the data obtained experimentally for the conductivity of AlN‐polyimide nanocomposite. Our results also demonstrate that as the filling factor is increased the phonon conductivity also increases. Possible applications are new types of nanocomposites with variable thermal conductivity by adjusting the filling factor and refractive indices of the nanoparticle and host material. These nanocomposites may be important components in the fabrication of thermal nanodevices used for heating and cooling.

      Summary
      • AbstractLower thermal conductivity and intrinsic electronic bandgap make large honeycomb dumbbell silicene/germanene prospective in future thermoelectrics.AbstractLarge honeycomb dumbbell (LHD) silicene/germanene was recently found to be the ground state of two-dimensional (2D) silicon and germanium, which was much more stable than the well-known low buckled (LB) silicene/germanene (Matusalemet al.,Phys. Rev. B,92, 045436 (2015)). The existence of an intrinsic band gap of LHD silicene/germanene makes them prospective in future thermoelectric devices. In this work, lattice thermal conductivity (κ) of the LHD silicene/germanene is investigated systematically by solving the phonon Boltzmann transport equation with interatomic force constants extracted from first-principles calculations, and compared with that of low buckled (LB) silicene/germanene. It is intriguing to find that, as compared with LB silicene, although the much flatter structure of the LHD silicene/germanene leads to a significantly larger portion of the flexural modes to the overall thermal transport, theκof the LHD silicene/germanene is only 5.9/1.6 W m−1K−1, which is substantially lower than that of the LB silicene/germanene. We found that the volumetric specific heat, group velocity square and the phonon lifetime of the LB silicene are all larger than that of the LHD silicene/germanene, with group velocity playing the dominant role, which is further linked with the higher Young's modulus of LB silicene. Besides, the difference in phonon lifetime is further explained in terms of the potential energy change. The trend of the root mean-square displacement values and the phonon anharmonicity is opposite to that of the normalized mean lifetime, which is physically justified, as larger displacements will lead to stronger anharmonicity and reduced lifetimes. The intrinsic ultralowκof the LHD silicene/germanene makes it prospective for thermoelectrics in the future.

      Summary
      • AbstractPhonon‐assisted anti‐Stokes emission and its stimulated emissionin polar semiconductor ZnTe are demonstrated via the annihilation of phonons as a result of strong exciton–phonon coupling. The findings are not only important for developing high‐power radiation‐balanced lasers, but are also promising for manufacturing ultraefficient solid‐state laser coolers.

      Summary
      • AbstractOwing to the bistable character of the single molecular magnet (SMM), it can generate 100% spin-polarized currents even connected with normal (N) leads. In this work, we study the phonon-assisted spin current in N-SMM-N systems. We mainly focus on the interplay of SMM's bistable character and electron-phonon coupling. It is found that when SMM is trapped in one of the lowest bistable states, it can generate phonon-assisted spin-polarized currents. At the up-spin transport channel, it is accompanied by a phonon-assisted up-spin current, while at the down-spin transport channel, it is accompanied by a phonon-assisted down-spin current.

      Summary
      • AbstractStrong electric‐field‐induced enhancement of the thermal emission rate of holes from the doubly ionised charge state of the ΕL2 defect was revealed with the double‐correlation deep‐level transient spectroscopy in p‐type GaAs crystals of various crystallographic orientations. The observed enhancement, by over four orders of magnitude of the emission rate, was analysed in a model of phonon‐assisted tunnel ionisation. Similar dependences of the hole‐emission rate on the electric‐field intensity received for the electric‐field directions parallel to three main crystallographic axes evidence for tetrahedral symmetry of the defect, which is consistent with its identification as the isolated arsenic antisite defect.

      Summary
      • AbstractA theory of low-temperature phonon-drag thermopowerSgin three-dimensional (3D) Dirac semimetals has been developed considering screened electron–phonon deformation potential coupling. Numerical investigations ofSg, in the boundary scattering regime for phonons, are made in 3D Dirac semimetal Cd3As2,as a function of temperatureTand electron concentrationne.Sgis found to increase rapidly for aboutT  <  1 K and nearly levels off for higherT. It is also seen thatSgincreases (decreases) with decreasingneat lower (higher)T(<2 K). A screening effect is found to be very significant, strongly affectingTandnedependence for about  <1 K and becoming negligible at higher temperature. In the Bloch–Gruneisen (BG) regime the power lawsSg~T8(T4) andSg~<inline-formula><tex-math></tex-math><named-content></named-content></inline-formula><inline-formula><tex-math></tex-math><named-content></named-content></inline-formula>with (without) screening are obtained. These laws with respect toTandneare, respectively, characteristics of 3D phonons and Dirac 3D electrons. Comparison with diffusion thermopowerSdshows thatSgdominates (and is much greater than)Sdfor aboutT  >  0.2 K. Herring’s lawSgμp~T −1, relating phonon limited mobilityμpandSgin the BG regime, is shown to be valid in 3D Dirac semimetals. The results obtained here are compared with those in 3D semiconductors, low-dimensional semiconductor heterojunctions and graphene. We conclude thatne-dependent measurements, rather thanT-dependent ones, provide a clearer signature of the 3D Dirac semimetal phase.

      Summary
      • AbstractPhonon-glass electron-crystal (PGEC) behaviour is realised in La0.5Na0.5Ti1–xNbxO3thermoelectric oxides.AbstractPhonon-glass electron-crystal (PGEC) behaviour is realised in La0.5Na0.5Ti1−xNbxO3thermoelectric oxides. The vibrational disorder imposed by the presence of both La3+and Na+cations on the A site of the ABO3perovskite oxide La0.5Na0.5TiO3produces a phonon-glass with a thermal conductivity,κ, 80% lower than that of SrTiO3at room temperature. Unlike other state-of-the-art thermoelectric oxides, where there is strong coupling ofκto the electronic power factor, the electronic transport of these materials can be optimised independently of the thermal transport through cation substitution at the octahedral B site. The lowκof the phonon-glass parent is retained across the La0.5Na0.5Ti1−xNbxO3series without disrupting the electronic conductivity, affording PGEC behaviour in oxides.
