Abstract

A mercury compound such as mercury telluride or mercury cadmium telluride is deposited upon a substrate by chemical vapor deposition, with dissociation of the organic compounds accelerated by laser energy. The mercury-containing compound is preferably divinylmercury, which dissociates under intense light of 248 nanometers wavelength to deposit mercury in combination with the codeposited element. The laser-assisted chemical vapor deposition is accomplished at 100.degree. C. to 195.degree. C., preferably 165.degree. C., without the deposition of carbon contaminants.
