<p>A method for chemical vapor deposition of materials containing tellurium, such as cadmium telluride and mercury cadmium telluride, wherein the reactant source of the tellurium is a tellurophene or methyltellurol. These reactant sources have high vapor pressures, and the reactant source vapors emitted from the reactant sources have decomposition temperatures of less than about 300°C, so that deposition may be accomplished at low temperatures of about 250°C. The reactant source vapor containing tellurium is mixed with a reactant source vapor containing another substance to be codeposited, such as dimethylcadmium or dimethylmercury, and contacted with a substrate maintained at the deposition temperature, the deposition being preferably accomplished in an inverted vertical chemical vapor deposition reactor (10).</p> |
