Abstract

Variations in the morphology of an InSe surface caused by air oxidation and the influence of the oxide-layered-semiconductor heteroboundary on the photoelectric properties of the In 2 O 3 -InSe structure were studied. It is found that an ordered nanosized heteroboundary can form as a result of oxidation of the layered InSe semiconductor and that this heteroboundary determines the high photosensitivity of the In 2 O 3 -InSe heterostructure in the spectral region of exciton absorption at room temperature.
