Abstract

The lattice thermal conductivity for CdS compound has been calculated over the temperature range ( 1-300k ) , Using Awad model . As The study used the correction formula in dispersion relation and distribution function for the calculation of the conductivity . The calcutations are in a good agreement with the experimental values of the lattice thermal conductivity , especially in the maximum point of the conductivity curve . This paper studies the change effects in the relaxation rates of phonon scattering by the boundaries , point defects , tri and quadrant phonon dispersion on the lattice thermal conductivity for both transverse and longitudinal phonons .
