Ab initio study of structural and electronic properties of ZnSnAs2		  pdf 

ABSTRACT

The structural and electronic properties of ZnSnAs2 crystal were studied by DFT-MGGA method within meta-General Gradient Approximation using Atomistix ToolKit program software. The electron-ion interactions were treated by the Fritz-Haber-Institute and Hartwigsen-Goedecker-Hutterion norm-conserving ionic pseudopotentials. The TB09LDA exchange-correlation functional, Double Zeta Polarized and Tier3 basis sets were used in resent calculations. First-principle studied reveal that the valence band maximum and conduction band minimum located at the Γ(0, 0, 0) symmetric point.

Keywords: ZnSnAs2, band structure, density of states (DOS), Density Functional Theory (DFT), meta-Generalized Gradient Approximation (MGGA).
