    • Absorption and photoconductivity spectra of Ag 2GeS 3 crystal: Experiment and theory 

      Ali Hussain, Reshak, Prof. Dr.; Auluck, Sushil, Dr.; Piasecki, Michał M.; Myronchuk, G. L.; Parasyuk, O.; Kityk, Iwan V; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr. (Elsevier B.V., 2012-07)
      Spectral features of polycrystalline Ag 2GeS 3 samples synthesized from high-purity elements (at least 99.99 wt.% purity) in quartz ampoules evacuated to 0.1 Pa were explored. The band energy gap of Ag 2GeS 3 crystals ...
    • Electronic spectral parameters and IR nonlinear optical features of novel Ag 0.5Pb 1.75GeS 4 crystal 

      Kogut, Yu; Khyzhun, Oleg Yu; Parasyuk, Oleg V.; Ali Hussain, Reshak, Prof. Dr.; Lakshminarayana, Gandham; Kityk, Iwan V.; Piasecki, Michał M. (Elsevier B.V., 2012-09)
      In this paper, we report on novel Ag0.5Pb1.75GeS4 single crystals grown by the Bridgman–Stockbarger method. For these crystals we have performed X-ray photoelectron spectroscopy (XPS) studies of the valence-band and ...
