| Abstract: | The random network model for amorphous alloys proposed by White has been developed for some selenium-based amorphous semiconductors (GeSe and AsSe) annealed or irradiated with light. The model suggests that the photo-bleaching and the photo-darkening observed in these systems may be due to changes in the numbers of bonds. |
