Laser Illumination Influence on the Optical Characteristics of As40S60-xSex (0 ≤ x ≤ 15) Films
Journal Title: Фізика і хімія твердого тіла - Year 2014, Vol 15, Issue 4
Abstract
The results of investigation of the As40S60-xSex amorphous films transmission spectra depending on thickness, exposure and heat treatment conditions are given. It was established that the increase of Se content in films composition, illumination and annealing of films leads to the absorption edge shift into the longwave spectral region. The values of pseudogap width Eg and refractive index n are determined. Maximum changes of optical characteristics are found for As40S48Se12 films and take place under laser illumination of high intensity and at short illumination times. Optical characteristic changes of films are caused by photo-thermostructural transformations taking place in them under illumination and annealing.
