Structure and Thermoelectric Properties of Pb-Sb-Te, Pb-Bi-Te Vapor-Phase Condensates on Glass Substrates

Journal Title: Фізика і хімія твердого тіла - Year 2014, Vol 15, Issue 2

Abstract

The results of ACM- research of processes of structure and thermoelectric properties of vapor-phase condensates doped by Sb and Bi Lead telluride and solid solutions PbTe-Sb2Te3, PbTe-Bi2Te3, deposited on substrates of polished glass have been proposed. The influence of the deposition time τ = (3-75) s with (thick condensate ) on the characteristics of individual nanoformation and change of thermoelectric parameters. It is shown that the main mechanism of nucleation is Folmera –Weber mechanism of individual nanoclusters formation and implementation processes nukleatsiy, aggregation and koalestsentsiy. A significant impact of donor impurities Sb and Bi and "giant" value of Seebeck coefficient S = (800-1400) mV/K of solid solutions has been found. A crystal doping and mechanisms of formation of solid solutions of the studied condensates have been proposed. Specified on the dominance of substitution of cationic impurities of the crystal lattice of PbTe ( ).
