“…The calculated κ natural given by the different lattice constants for each indium-V compound are compared in Figure 7. Figure 7 shows the calculated κ L vs. temperature for the indium-V compounds with experimental data for InP (black circles [59], squares [60], diamond [61], and triangle [62]), InAs (red circles [63], squares [64], diamond [65], and triangles [66]), and InSb (blue circles [56], squares [67], and triangles [68]). The isotope effect is small in the indium-V compounds so we show only the calculated κ natural in Figure 7.…”

“…Experimental data is shown for κ L of GaSb (black circles [56]), GaAs (green circles [47] and green triangles [48]), and GaP (red circles [51] and red triangles [52]). For GaN the lattice constant determined by energy minimization was increased ~1% to give better agreement with the experimental phonon dispersion as discussed in Ref.…”

We use a recently developed ab initio approach to calculate the lattice thermal conductivities of compound semiconductors. An exact numerical solution of the phonon Boltzmann transport equation is implemented, which uses harmonic and anharmonic interatomic force constants determined from density functional theory as inputs. We discuss the method for calculating the anharmonic interatomic force constants in some detail, and we describe their role in providing accurate thermal conductivities in a range of systems. This first-principles approach obtains good agreement with experimental results for well-characterized systems (Si, Ge, and GaAs).We determine the intrinsic upper bound to the thermal conductivities of cubic aluminum-V, gallium-V, and indium-V compounds as limited by anharmonic phonon scattering. The effects of phonon-isotope scattering on the thermal conductivities are examined in these materials and compared to available experimental data. We also obtain the lattice thermal conductivities of other technologically important materials, AlN and SiC. For most materials, good agreement with the experimental lattice thermal conductivities for naturally occurring isotopic compositions is found. We show that the overall frequency scale of the acoustic phonons and the size of the gap between acoustic and optic phonons play important roles in determining the lattice thermal 2 conductivity of each system. The first-principles approach used here can provide quantitative predictions of thermal transport in a wide range of systems. 63.20.kg,

“…This step is represented by the right hand side term of the BTE (f 0 − f )/τ (ω, T ) and brings the 150 system back to equilibrium after the drift phase by modifying the phonon's properties. It takes into account the phonon scattering due to impurities and anharmonic processes (phonon-phonon interactions) thanks to the semi-empirical lifetime of Holland [55]. Thus, the Normal and Umklapp processes are differentiated.…”

Materials with low thermal conductivity, high electrical conductivity, and high Seebeck coefficient are required for high efficiency solid-state energy conversion. Although semiconductors are the best thermoelectric materials, they rarely have the desired properties. Nanostructures such as superlattices, quantum wires, and quantum dots provide novel methods to improve the solid-state energy conversion efficiency through electron and phonon transport engineering. In this paper a semiconducting superlattice consisting of periodic nano layers of silicon and germanium has been studied. Due to nano scale effects, conductive heat transfer does not satisfy the Fourier's law of thermal conduction, and the equation of phonon radiative transfer has been solved instead. A computational method similar to Discrete Ordinate Method in thermal radiation was implemented, and the equations were solved numerically. The results show that the thermal conductivity of the nano structure is much lower than the macro structures with the same aspect ratio. It was also noticed that with a constant ratio of layers' thicknesses, more reduction in layers' thicknesses causes more temperature jump at the interfaces and consequently more reduction in the effective thermal conductivity, that finally improves the thermoelectric properties. It was also shown that the effective thermal conductivity depends on the density of interfaces per unit length of the superlattice, when the heat flow direction is perpendicular to the layers.
