Étude Numérique Des Propriétés Optoélectroniques Des Alliages Semi-conducteur Ternaire Cubiques À Base De Strontium.
Résumé: Recently, there is considerable interest in II–VI semiconductors and their alloys due to their application in photovoltaic devices, as electro-optical and optoelectronic crystals and their applications to the recent realization of luminescent diodes. This motivated several physicists to study these compounds, their structural and thermodynamic properties in this family and their alloys and revise many fundamental physical properties based on the calculations of Ab Initio. In this work a numerical study of structural, electronic and optical properties will be carried out. To contribute to a better understanding of the optoelectronic properties of semiconductors of type II-VI we will use the code WIEN2k with the approximation of the generalized gradient of Perdew-BurkeErnzerhof (PBE-GGA) and the correction Tb-mBJ (The Tran and Blaha modified Becke-Johnson potential). Finally, an application will be made on ternary materials based on Strontium to clearly show the efficiency of this work where it will be compared with other results.
