Structure and optical properties of GaSe-CdSe composites driven by Cd inetrcalation in gase lamellar crystals

A new composite material composed of GaSe and CdSe has been obtained by treatment of GaSe single-crystal lamellas in Cd vapors at temperatures of 773853 K and intercalation of Cd interlayers. The structure and optical properties of the GaSe-CdSe composite material have been studied. The content of...
