The kinetics describing in-situ photodarkening in amorphous As100-xSex thin films for different compositions as well as for various thicknesses were studied. It was shown this kinetics strongly depended on penetration depth parameter (the inverse value of the absorption coefficient): in the case that films thickness is greater than penetration depth, the photodarkening kinetics can be described by stretched exponential function. In contrast, if film thickness is less than penetration depth, the stretched exponential relaxation kinetics tents towards simple exponential one. |
