Abstract
We have analyzed the phonon conductivity of the II-VI compound CdTe and the III-V compound InSb in the temperature region 2-300°K on the basis of a modified Holland's formulation. The formulation considers quadratic and cubic frequency-wave-vector relationships for the longitudinal and transverse phonons, respectively. Guthrie's suggestion for two-mode heat conduction for three-phonon relaxation times and Pomeranchuk's idea for four-phonon relaxation time in the high-temperature region have also been incorporated. The obtained results are in fair agreement with the existing experimental data.Keywords
