Abstract

The heat-pulse technique was employed to study the heat transfer in laser-pulse excitation in a high-purity grain-oriented CdTe growth by multiple sublimation. Comparison of the heat pulses obtained in the experiment with the results of calculations by the Monte Carlo method allowed one to evaluate the mean free path of the acoustic phonons in this material. It is proposed on the basis of the results obtained that the scattering by planar defects (grain boundaries and twinning planes) is the main mechanism of phonon scattering at low temperatures.
