Surface nanostructuring of CuIn1−x Ga x Se2 films using argon plasma treatment

In this work we report a phenomenon of the self-formation of nanostructure arrays during low-energy inductively coupled argon plasma treatment of the surface of copper indium gallium diselenide films grown by different methods on glass substrates. Selenization, pulsed laser deposition and multistage co-evaporation technological methods were used for the growth of polycrystalline CuIn1−x Ga x Se2 (0.04 ≤ x ≤ 0.45) films. The plasma treatment of …
