The structure, optical and electrical properties of vapor-phase condensates PbTe:Bi on mica

Abstract

Presented by results of the study of structure formation processes in vapor-phase condensates PbTe: 0,1 аt. % Bi, obtained by evaporation sample of the synthesized compounds in open vacuum and de  position of vapor on fresh chips (0001) mica-muscovite brand STA. Established features the ir nu  cleation and growth at different temperatures TS = (420—470) K and time τ = (240—1200) s depo sition. Investigated spectral optical properties in the frequency range (225—6000) cm–1 and the ele ctrical parameters of the structure. Clarified the mechanisms of donor influence impurities of bismuth on the electrical properties of condensates.
