Influence of X-ray irradiation on the optical absorption edge and refractive index dispersion in Cu6PS5I-based thin films deposited using magnetron sputtering
Journal Title: Semiconductor Physics, Quantum Electronics and Optoelectronics - Year 2017, Vol 20, Issue 2
Abstract
Cu6PS5I-based thin films were deposited using non-reactive radio-frequency magnetron sputtering. Structural studies of thin films were performed by scanning electron microscopy, their chemical composition were determined using energy-dispersive X-ray spectroscopy. As-deposited thin films were irradiated with wideband radiation of Cu-anode X-ray tube at different exposition times. Optical transmission spectra of X-ray irradiated Cu5.56P1.66S4.93I0.85 thin films were measured depending on irradiation time. The Urbach absorption edge and dispersion of refractive index for X-ray irradiated Cu5.56P1.66S4.93I0.85 thin films were studied. It has been revealed the nonlinear decrease of energy pseudogap and nonlinear increase of refractive index with increase of X-ray irradiation time.
