PHOTOSENSITIVITY IN EPITAXIAL PBS FILMS,

Abstract

A study has been made of the photosensitivity in epitaxial PbS films which were sensitized by heat treatments in air or sulfur vapor. The sensitizing process results in the formation of narrow lines of material which are more p-type than the host film. The resultant junctions are responsible for the photosensitivity. Various properties of the epitaxial films were determined and compared to the corresponding properties of the well-known polycrystalline PbS detectors. (Author)
