Abstract
The specific features of experimental data on kinetic phenomena in p-type A2V B3VI materials and the results of calculations related to these phenomena in the one- and two-band models are discussed. It is possible to correlate the calculations with the experiment in the two-band model with consideration for interband hole scattering and to estimate the parameters of their experimental spectrum. The reflectance spectra of p-Sb2Te3–xSex crystals in the range 400–7000–1 are reported. The spectra are approximated in the context of the Drude–Lorentz theory which takes into account the plasma vibrations of holes.
