CRYSTAL STRUCTURE OF SECONDARY COMPOUNDS

Abstract

In this article, it is explained that as a result of the melting of secondary alloys, the formation of a continuous series of solid solutions and the formation of parallel layers, the atoms of the layer and the planar hexagonal lattice formed by them. Among the chalcogenides that are components of these solid solutions, bismuth telluride has been studied in the most detail. This is because, firstly, bismuth telluride itself has very high thermoelectric parameters and was widely used as a working material in early models of thermoelectric devices.

Among the chalcogenides that are components of these solid solutions, bismuth telluride has been studied in the most detail. This is because, firstly, bismuth telluride itself has very high thermoelectric parameters and was widely used as a working material in early models of thermoelectric devices. Secondly, it was possible to make it p- and n-type with a doping agent. Finally, bismuth telluride was easy to prepare in the form of very perfect single crystals. There is no single point of view on the regulation of processes in these considered solid solutions, and there is no detailed information on the shift in stoichiometry. This is explained by the multicomponent nature of materials and the presence of various interatomic interactions in the crystal lattice.
