Physical-Chemical Properties and Mechanisms of Tin Telluride Doped by Bismuth
Journal Title: Фізика і хімія твердого тіла - Year 2014, Vol 15, Issue 3
Abstract
The analysis of features of equilibrium diagrams and homogeneity range of the compound SnTe, character defective subsystem of crystal structure, physical and chemical properties of SnTe and SnTe:Bi are shown. On the basis of experimental studies of the concentration dependence of the lattice constant and thermoelectric parameters of SnTe: Bi and defined possible mechanisms of the interaction between dopant and main matrix: metal chalcogen substitution and increasing of the homogeneity range with formation of vacancies in cationic sublattice.
