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 ... -
Band structure, density of states, and crystal chemistry of ZrGa₂ and ZrGa₃ single crystals
Ali Hussain, Reshak, Prof. Dr.; Lakshminarayana, Gandham; Ebothe, Jean; Fedorchuk, Anatolii O.; Fedyna, M.F.; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Mandracci, P.; Auluck, Sushil, Dr. (Elsevier, 2013-04)Using FP-LAPW Method we have performed calculations of the band structure of the ZrGa₂ and ZrGa₃ crystals. The all-electron full potential linearized augmented plane wave method was used to solve the Kohn Sham DFT equations. ... -
Influence of different exchange correlation potentials on band structure and optical constant calculations of ZrGa2 and ZrGe2 single crystals
Ali Hussain, Reshak, Prof.Dr.; Fedorchuk, Anatolii O.; Lakshminarayana, Gandham; Alahmed, Zeyad A.; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Auluck, Sushil (Elsevier B.V., 2013-10)The all-electron full potential linearized augmented plane wave method was used to solve the Kohn Sham DFT equations. We have employed different approximations for the exchange correlation potentials, namely: LDA, GGA and ...
