The alloys are described by considering configurations in 16-atom supercells, corresponding to [GRAPHICS] conventional cubic cells. The lattice parameter, bulk modulus, bulk modulus derivation, the energy band gap and bowing parameter are obtained as a function of Sc concentration for ternary alloys [GRAPHICS] . Our studies focus on the concentration dependence of the electronic band structure and bowing parameter of these alloys. We found that [GRAPHICS] composition affects strongly bowing parameter and the band gap increases with increasing Sc concentration for [GRAPHICS] in the zinc-blende structure. The results also show that the energy band gap and bowing parameter of the [GRAPHICS] alloys can be obtained by a third-order polynomial equation, [GRAPHICS] and [GRAPHICS] , respectively.eninfo:eu-repo/semantics/closedAccessSemiconductorBowing ParameterZinc-Blende AlloysArticle9411Q3Q3724731WOS:000346296100007
