Аннотация:The T-x phase diagram along the PbTe-VTe2 join of the Pb-V-Te system has been studied. Vanadium-doped lead telluride crystals have been grown, and the longitudinal vanadium and carrier profiles in the crystals have been investigated. The temperature dependences of resistivity for the crystals lend support to the conclusion drawn earlier that PbT < V > is in a semi-insulating state at low temperatures. The crystals offer a high 20-K electron mobility, on the order of 10(5) cm(2)/(V s), which attests to high electrical homogeneity of the material and stabilization of the Fermi level.
