mobility, Seebeck coefficient, specific electrical conductivity, effective massAbstract
The paper presents a comparative analysis of the charge carrier mobility in PbTe calculated using expressions derived from the Drude-Sommerfeld model and the model of a nondegenerate semiconductor with parabolic zones. The mobilities were calculated as functions of the experimentally determined Seebeck coefficient and specific electrical conductivity. The results are compared with the corresponding data obtained in the relaxation time approximation.
