Abstract:
Films of substitutional solid solutions of the Cu$_2$Se–In$_2$Se$_3$ system containing up to 7.5 at.% In have been obtained by chemical deposition from aqueous media. The composition, structure, and morphology of the films have been studied. Data of X-ray diffraction and X-ray photoelectron spectroscopy showed that copper in the solid solution occurs in a single-valence state (Cu$^+$). The deposited layers possess a globular morphology and are nanostructured.
