Abstract

The article introduces Hi input to p -type Bi₂Te₃ thermoelectric materials under inert gas pressure and presents the results of the study of electrical conductivity, Hall coefficients, thermoelectric and galvanomagnetic properties in the temperature range 77 ÷ 300K. The study of thermoelectric properties has shown that in order to explain the temperature dependence of the heat transfer parameter and the ratio of thermoelectric power to temperature, it is necessary to take into account the complex structure of the valence zone and the contribution of heavy cavitation in transport. It is shown that in order to explain the temperature dependences of the scattering parameter and the ratio of thermoelectric power to temperature, it is necessary to take into account the complex structure of the valence band and the contribution of heavy holes to transport phenomena. The estimates of the band parameters in the framework of the two-band model give the values of the effective mass of holes on the order of the mass of a free electron and the energy gap between nonequivalent extrema on the order of several hundredths of an eV.
