Abstract:In this study, structural, electronic, optical and thermoelectric aspects of Zinc Sulfide (ZnS) and Zinc Telluride (ZnTe) have been explored in detail. These calculations have been done by utilizing FP‐LAPW method via Density Functional Theory (DFT). In order to attain accurate band gaps, opto‐electronic properties are evaluated with modified Becke Johnson potential (mBJ). From band structure plots, both ZnS and ZnTe reveals direct (Γv–ΓC) band gap semiconductors in nature with bandgap value equal to 3.5 and 2… Show more
