WebMay 1, 2002 · The refractive index of evaporated films was found to show a substantial thickness dependence. Evaporated films of higher thickness usually show a columnar grain structure with reduced density, which leads to a lower refractive index and causes a negative inhomogeneity of the refractive index. WebReactive gases can also be used to sputter compounds. The compound can be formed on the target surface, in-flight or on the substrate depending on the process parameters.
