Effect of deposition temperature on the structure and optical properties of zinc-selenide films produced by radio-frequency magnetron sputtering

The effect of the condensation temperature on the growth rate, structure, and optical properties of zinc-selenide films produced by radio-frequency magnetron sputtering is studied. As the deposition temperature is increased, the film thickness decreases. Polycrystalline zinc-selenide films consist of a mixture of cubic and hexagonal phases, of which the cubic phase is dominant. A correlation between the refractive index and the crystallite size is shown.
