| Abstract | ||
| In this paper, we have calculated the lattice thermal conductivity for the compound CdTe at a temperature range (1.5-300K) , according to Awad model (Awad's formulas contains the contribution due to the transverse and longitudinal phonons).The study reveals a good agreement between the theatrical and experimental values of the lattice thermal conductivity. The percentage contribution of different phonon scattering relaxation rates in the total phonon scattering relaxation rate calculated for both modes of conduction. The effect of temperature exponent m(T) on the lattice thermal conductivity has been discussed in this paper. Furthermore , it has been found the transverse phonons in general make have the major contribution to the lattice thermal conductivity. Our results are in good agreement with other researchers. | ||
