“…One way is to compare of the experimental responses with those calculated by the Monte Carlo method [3]. As a result of such an analysis, one can understand the specific features of the phonon propagation and estimate the intensity of the elastic scattering of the nonequilibrium acoustic phonons by the point defects in the sample under study [4,5], the characteristic size of the grains constituting the sample [6], and so on.…”

The heat-pulse technique was employed to study the heat transfer in laser-pulse excitation in a highpurity grain-oriented CdTe grown 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.

“…We have previously used the known values of AL constants and varied As when modeling the propagation of the nonequilibrium acoustic phonons in silicon and diamond [4,5]. This allowed us to determine the constant As for the particular samples with unknown impurity content.…”
