Abstract

Cu6PS5I-based thin films deposited by magnetron sputtering were irradiated using wideband radiation of Cu-anode X-ray tube at different exposition times. Optical transmission spectra, Urbach absorption edge, and dispersion of refractive index for X-ray irradiated Cu5.6P1.7S4.9I0.8, Cu6.4P1.1S4.6I0.9 and Cu8.0P0.7S3.6I0.7 thin films were studied. The decrease of energy pseudogap and increase of refractive index with increase of X-ray irradiation time is observed

Keywords: thin film, magnetron sputtering, X-ray irradiation, optical absorption, refractive index
