| Abstract: | It has been shown that uncertainties in the interpretation of experimental data on transport phenomena in Sb2Te3 are resolved in the two-band model with the consistent inclusion of the interband hole scattering. The performed calculation is in quantitative agreement with the experimental data in the temperature range from 77 to 400 K for the following parameters of the band spectrum: the effective mass of the density of states of light holes m d1 ≈ 0.6m 0 (where m 0 is the free electron mass), the effective mass of the density of states of heavy holes m d2 ≈ 1.8m 0, and the energy gap between nonequivalent extrema of the valence band ΔE v(T) ≈ 0.15–2.5 × 10?4 T eV. |
