An ab initio density functional study of the optical functions of 9-Methyl-3-Thiophen-2-YI-Thieno [3,2e] [1,2,4] Thriazolo [4,3c] Pyrimidine-8-Carboxylic Acid Ethyl Ester crystals
Ali Hussain, Reshak, Prof. Dr.; Kityk, Iwan V.; Rabah, Khenata, Prof. Dr.; Yarub, Al-Douri, Assoc. Prof. Dr.; Auluck, Sushil, Dr. (Elsevier B.V., 2012-09)An ab initio investigation of the optical constants of 9-Methyl-3-Thiophen- 2-YI-Thieno [3,2e] [1,2,4] Thriazolo [4,3c] Pyrimidine-8-Carboxylic Acid Ethyl Ester crystal is performed within a framework of local density ... -
Amino acid 2-aminopropanoic CH 3CH(NH 2)COOH crystals: Materials for photo- and acoustoinduced optoelectronic applications
Ali Hussain, Reshak, Prof. Dr.; Lakshminarayana, Gandham; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Kityk, Iwan V.; Auluck, Sushil, Dr.; Berdowski, Janusz M.; Tylczynski, Zbigniew (Springer Science+Business Media, LLC, 2012-10)Photo-induced treatment of L-alanine single crystals grown by slow evaporation method at an ambient temperature was performed using a 25 ps Nd:YAG pulsed laser in the presence of an external acoustic filed. The changes of ... -
Crystallochemical affinity and optical functions of ZrGa2 and ZrGa3 compounds
Ali Hussain, Reshak, Prof. Dr.; Kityk, Iwan V.; Ebothe, Jean; Fedorchuk, Anatolii O.; Fedyna, M.F.; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Auluck, Sushil, Dr. (Elsevier B.V., 2012-01)The influence of crystallochemical affinity for crystals ZrGa2 and ZrGa3 on the optical properties was studied. We have calculated dispersion of optical constants ε2average(ω). We have established that application of ... -
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 ... -
