Density functional study of optical properties of beryllium chalcogenides compounds in nickel arsenide B8 structure
Yarub, Al - Douri; Baaziz, H.; Charifi, Z.; Ali Hussain, Reshak, Prof. Dr. (Elsevier B.V., 2012-02-01)The structural, electronic and optical properties of beryllium chalcogenides BeS, BeSe and BeTe using the full-potential linear augmented plane wave (FP-LAPW) method are investigated. The exchangecorrelation energy within ... -
The effect of chalcogen atom on the structural, elastic, and high-pressure properties of XY compounds (X=La, Ce, Eu, and Y=S, Se, and Te): An ab initio study
Charifi, Z.; Baaziz, H.; Saeed, Yasir; Ali Hussain, Reshak, Prof. Dr.; Soltani, F. (WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim., 2012-01)The B1 (NaCl) and B2 (CsCl) structure of rare-earth monochalcogenides XY (X=La, Ce, Eu, and Y=S, Se, and Te) were investigated with the full-potential linearized-augmented plane wave (FP-LAPW) scheme in the frame of the ... -
Further optical properties of CdX (X¼ S, Te) compounds under quantum dot diameter effect: Ab initio method
Yarub, Al - Douri; Baaziz, H.; Charifi, Z.; Khenata, R.; Uda, Hashim, Prof. Dr.; Al-Jassim, M. (Elsevier Ltd., 2012-09)For energy band calculations, the indirect energy gap (G X) is calculated using density functional theory (DFT) of the full potential-linearized augmented plane wave (FP-LAPW) method as implemented in WIEN2K code. The ... -
The influence of the lattice relaxation on the optical properties of GaNxAs1-x alloys
Ali Hussain, Reshak, Prof. Dr.; Charifi, Z.; Baaziz, H. (Elsevier Ltd., 2013-04)We have investigated the optical properties of the ternary alloys GaNxAs1-x (x=0.25, 0.5 and 0.75) without (we call it as case 1) and with (case 2) the lattice relaxation, using the full potential-linearized augmented plane ... -
Structural and electronic properties of GaN x As 1-x alloys
Baaziz, H.; Charifi, Z.; Ali Hussain, Reshak, Prof. Dr.; Hamad, Bothina A.; Yarub, Al-Douri (Springer-Verlag., 2012-03)The structural and electronic properties of cubic GaN x As 1-x with N-concentration varying between 0.0 and 1.0 with step of 0.25 were investigated using the full potential-linearized augmented plane wave (FP-LAPW) method. ...
