Abstract

The electro-photoinduced disappearance of Al from the surface of chalcogenide glassy film in Ni-As₂Se₃-Al and Ni-As ₂S₃-Al structures has been investigated. Induced diffusion of Al into chalcogenide films has not been revealed, and Al disappearance is shown to be due to photo-electroinduced oxidation of the Al layer in the humid air atmosphere. Al oxidation begins in the form of an island-like process. The phenomenon of polarized photodoping, characteristic of As₂S ₃-Ag structures, was not observed in the Ni-As₂S ₃-Al samples.
