The results of studies of structural and thermoelectric properties obtained by the powder pressing method of PbTe samples are presented. In order to interpret the obtained results, a theoretical calculation of the specific conductivity and the Seebeck coefficient was performed on the basis of a model that takes into account two types of free charge carriers. Conclusions have been made about the mechanisms of carrier scattering.
