<P>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 CuIn<SUB>1−<I>x</I> </SUB>Ga<SUB> <I>x</I> </SUB>Se<SUB>2</SUB> (0.04?≤?<I>x</I>?≤?0.45) films. The plasma treatment of the surface of the films grown by all three methods resulted in the plasma-assisted self-formation of arrays of uniform cylindrical or conical nanostructures with the surface density of (0.8–1.8)?×?10<SUP>11</SUP> cm<SUP>−2</SUP>. Using scanning electron microscopy, transmission electron microscopy and atomic force microscopy, we describe the morphological parameters and chemical composition of the fabricated nanostructures and discuss possible physical mechanisms of the observed plasma-assisted nanostructuring.</P>

The structural, compositional, morphological and optical properties of In2S3 thin films, prepared by thermal evaporation technique and annealed in sulfur ambient at different temperatures have been investigated. The grazing incident X-ray diffraction patterns have indicated polycrystalline form and predominantly cubic structure of annealed In2S3 films. The scanning electron microscopy revealed textured surface with uniformly distributed grains and the grain size increased with increase of annealing temperature. The optical parameters of the films have been determined using conventional transmission and reflection spectra as well as from surface photovoltage measurements.
