摘要：
The phase composition, electrical conductivity, and thermal EMF coefficient of PbTe with small CdSe impurities are studied, and relationships among these parameters are established. It is shown that the electrical conductivity and thermal EMF coefficient are minimal at the minimal lattice parameter of newly formed phases in the PbTe matrix (at a concentration of 0.5 mole%). A further increase in the concentration leads to the increase of these parameters. Isothermal annealing of the samples leads to an increase in the electrical conductivity and a slight decrease in the thermal EMF.
