Optical constants of As2Se3–Ag4SSe–SnTe amorphous thin films
Source abstract
Abstract
Abstract Amorphous thin films from the As2Se3–Ag4SSe–SnTe system were prepared by thermal vacuum evaporation from the corresponding bulk glasses. Their transmission, reflection, scattering and ellipsometric spectra were measured in the UV, VIS and NIR regions, and the results were mathematically simulated using the Tauc–Lorentz dispersion model in order to obtain the refractive index and extinction coefficient. The compositional dependence of the derived optical properties was found and discussed.
