Effect of the Sb/Se Ratio on the Structural and Electrical Properties of Sb x Se y Films

Abstract

Sb x Se y thin films were obtained from precursor of pure antimony and selenium granules evaporated in the temperature ranges from 980 to 1025°C for Sb and 415 to 470°C for Se by chemical molecular beam deposition method on glass substrates. It was found that the films consist mainly of the Sb x Se y phase and have a different Sb/Se ratio in the range from stoichiometry to 0.89. Controlling the fraction of components allows to change the orientation of crystallites, which, in turn, leads to changes in electrical conductivity.
