The influence of electron irradiation on a form of the intrinsic absorption edge at various doses was studied. The influence of the processes of structural disorder on the energy position and the absorption edge width was investigated. The optical data are interpreted in a Gody model.

Keywords: electron irradiation, absorption edge, chalcogenide glassy semiconductors, the Urbach rule, structural and dynamic disorder.
