Mercury cadmium telluride has been successfully grown by the photolysis of dimethylmercury, dimethylcadmium, and dimethyltelluride, using an ArF excimer laser operating at 193 nm as the radiation source. Growths were accomplished on CdTe substrates at a temperature of 150 °C, with a growth rate of 4 μm per hour. Films are shiny, and x‐ray diffraction indicates epitaxial growth. Secondary ion mass spectroscopy and infrared transmission measurements indicate that the composition of the initial films is Hg0.2Cd0.8Te. Details of the growth apparatus and additional data is presented.
