• The photostructural change in chalcogenide glasses can be understood as achange in the interband correlation of spatial potential fluctuations. A modelof reaction processes for this change is proposed, including the capture andrecombination of photogenerated electron-hole pairs and the transformation ofpotential fluctuations. By assu.ming appropriate forms for the reaction rates, thefollowing results are obtained. In the stationary condition under light illuminationthe degree of negative interband correlation increases with increasing light in-tensity and decreases with increasing temperature, while in thermal equilibritun(on annealing) in the dark it increases with increasing temperature. These fea-lures are consistent with recent experiments.
