In this paper the same work on obliquely deposited thin film is presented. Universal description for the kinetics of photoinduced volume change in chalcogenide glasses is proposed based on our results. Our model containing reversible (transient) and irreversible (metastable) parts for kinetics fits well the experimental results of both obliquely and flatly deposited a-AsSe thin films. Finally, we make a brief comment on stretched exponential function which could also provide a quite good fit to experimental data. (C) 2011 The Japan Society of Applied Physics},

To model the photoinduced volume changes the electron excitation and hole creation were treated independently within the framework of tight-binding formalism.
