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 ... -
Electronic structure of quaternary chalcogenide Ag₂In₂Ge(Si)S₆ single crystals and the influence of replacing Ge by Si: Experimental X-ray photoelectron spectroscopy and X-ray diffraction studies and theoretical calculations
Ali Hussain, Reshak, Prof. Dr.; Khyzhun, Oleg Yu; Kityk, Iwan V.; Fedorchuk, A. O.; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Auluck, Sushil, Dr.; Parasyuk, Oleg V. (American Scientific Publishers, 2013-04)Ag₂In₂GeS₆ and Ag₂InSiS₆ are two interesting quaternary-sulfide single crystals. Starting from our previous investigation on Ag₂In₂GeS₆ single crystals, the Ag₂In₂SiS₆ is investigated here. We demonstrate the effect of ... -
Photothermal poling of glass complexes Ag2S–Ga2S3–P2S5
Parasyuk, Oleg V.; Ali Hussain, Reshak, Prof. Dr.; Klymuk, T. L.; I.i., Mazurets; O.v., Zamuruyeva; G.l., Myronchuk; Owsik, Jan (Elsevier Ltd., 2013-10)The studies of the dc-electric field induced second harmonic generation (SHG) for fundamental wavelength of the Ag2S–Ga2S3–P2S5 using nanosecond Er:glass laser at wavelength 1540 nm and elevated temperatures (thermal poling) ... -
X-ray photoelectron spectrum, X-ray diffraction data, and electronic structure of chalcogenide quaternary sulfide Ag2In 2GeS6: Experiment and theory
Ali Hussain, Reshak, Prof. Dr.; Kityk, Iwan V.; Parasyuk, Oleg V.; Fedorchuk, Anatolii O.; Zeyad A., Alahmed; Nasser Saleh, Alzayed; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Auluck, Sushil, Dr. (Springer Science+Business Media, LLC, 2013-02)We report measurements of the X-ray diffraction and X-ray photoelectron spectrum on single crystals of Ag2In2GeS6. We also present first principles calculations of the band structure and density of states using the ...
