A study of the phase transitions, electronic structures and thermodynamic properties of Mg2X (X = Ge, Si and Sn) under high pressure
Autor: M. Guezlane, H. Baaziz, Z. Charifi, A. Belgacem-Bouzida, Y. Djaballah
Publikováno v: Journal of Science: Advanced Materials and Devices, Vol 2, Iss 1, Pp 105-114 (2017)
In this work, we theoretically investigate phase transitions, electronic structures and thermodynamic properties of Mg2X (X = Ge, Si and Sn) under high pressures. To reach this goal, the total energy has been calculated by using the full-potential li

Microstructured ZnO-ZnS composite for earth-abundant photovoltaics: Elaboration, surface analysis and enhanced optical performances
Autor: Nicolas Martin, Fayçal Djeffal, A. Benhaya, K. Benyahia, A. Bendjerad, Y. Djaballah, Hichem Ferhati
Publikováno v: Solar Energy. 218:312-319
In this paper, ZnO-ZnS composite structure is proposed as a new efficient and earth-abundant absorber material for thin-film solar cells (TFSCs). Promising elaboration strategy based on combining vacuum thermal evaporation technique and oxidation pro

Autor: H. Righi, O. Cheref, Y. Djaballah, M. Ghezali, M. Rabah, Ali H. Reshak, A. Belasri, A. Gani, D. Rached
Publikováno v: Chinese Journal of Physics. 64:174-182
We have conducted a first-principles study on the structural, electronic, optical and elastic properties of BeSiP2 and BeGeP2 chalcopyrite compounds. Using the density functional theory (DFT), implemented in both full potential linear muffin-tin orbi

Ab-initio investigation on the phase stabilities of Au-M Alloys (M = Na, K, Rb and Cs)
Autor: L Bennour, Y Djaballah, H Righi, D Bahloul
Publikováno v: Physica Scripta. 97:125703
Ab initio calculations were performed to investigate the structural stability, mechanical, and thermodynamic properties of all intermetallic compounds in the different formulas Au5M, Au2M, AuM, and AuM2 (M = Na, K, Rb, and Cs) in order to clarify the

First-Principles Calculations of Defect Structures in B2 AlCo and GaCo
Autor: Y. Djaballah, Aissam Hidoussi, El-djemai Belbacha, A. Belgacem-Bouzida, Abdelhak Kerboub
Publikováno v: Journal of Phase Equilibria and Diffusion. 38:143-150
First-principles electronic structure calculations have been performed for defect structures in nonstoichiometric B2 AlCo and GaCo. To determine the type of constitutional defects, the compositional dependence of the energy of formation and lattice p
