Plasma enhanced chemical vapor deposition of epitaxial mercury telluride

Abstract
Epitaxial layers of mercury telluride were deposited onto cadmium telluride substrates at 85 °C using a glow discharge to enhance the reaction between dimethylmercury and dimethyltelluride. Hall-effect measurements showed the material to be n type with room-temperature and 77 K carrier concentrations of 5.0×1017 and 1.0×1017 cm−3, respectively: room-temperature Hall mobility was 22 000 cm2/V s and 77 K mobility was 52 000 cm2/V s.
