Essay

On the basis of complex experimental researches of physical and chemical properties and the crystal and chemical analysis of the defect subsystem, the quasichemical equations which take into account the complex spectrum of point defects in the crystals of n- and p-PbTe (PbSe) have been offered p-SnTe, PbTe:Bi, PbSe:Bi, as well as crystal-quasichemical formulas of soslid solutions of Pb-Sb(Bi)-Te, Pb-Sb(Bi)-Se,Sn-Sb(Bi)-Te. We have determined the mechanisms of alloying and formation of soslid solutions which makes the scientific basis of the guided synthesis of semiconductor materials with the beforehand preset parameters necessary for the settlement of practical tasks while creating electronic and thermo-electrical devices.
