Thermal Conductivity of Zincblende Crystals

Authors: Amelia Carolina Sparavigna

Among materials having zincblende lattices, we find some that are characterized by a high thermal conductivity. This is a quite important feature for their application in semiconductor technologies and related devices. In this paper, we will discuss the thermal conductivity of two zincblende crystals (SiC and GaAs), stressing the role of lattice vibrations in producing high values of conductivity and of lattice defects in reducing it. In the framework of a model dealing with phonon dispersions and reliable scattering mechanisms, we will show how lattice thermal conductivity can be estimated from the Boltzmann Transport Equation in the case of any zincblende crystal.
