Charge-Transfer Processes in (SnS)1 – x(PrS)x Alloys

Abstract

Interactions in the SnS-PrS alloy system have been studied. On the basis of the results of complex physicochemical analysis, the interval of PrS solubility in SnS is determined. The microrelief of the surface of Pr Sn1− S single crystals is analyzed using a scanning probe microscope operating in the atomic-force regime. The electrical conductivity and the Hall coefficient are researched in a broad temperature interval of 80-800 K. The charge-transfer processes in the objects concerned are analyzed. K e y w o r d s: solid solutions, chalcogenides, electrical conductivity, donor, Hall coefficient, valence band, light and heavy holes.
