Chaviak I. Growth processes, structure and transport phenomena in Tin Telluride vapor-phase nanocondensates

The basic topological properties of nanostructured surfaces SnTe and SnTe:Bi condensates, obtained by vapor-phase methods for various technological factors and deposited on monocrystalline, polycrystalline, and amorphous substrates using was defined on the base of AFM results. The influence of external fields on the structural characteristics of Tin Telluride condensates cause to change in the phase composition so they substructure complex parameters. There were investigating the dependences of electrical parameters of the condensates from the growing conditions, namely, temperature, thickness and structural characteristics. The conditions of formation of vapor-phase nanocondensates with optimal thermoelectric parameters (thermoelectric power S2 ? 18 W/(K2cm) and ? 30 W/(K2cm) for pure and Bithmuth doped SnTe, accordingly) was obtained for creating p-elements of micromodules of the thin film thermoelectric generators.
