Tuning the electronic and optical properties of the sphalerite by adsorbing halogen and alkali metals

open access: yesIET Optoelectronics, 2021
TThe electronic and optical properties of sphalerite (ZnS) are modulated by adsorbing alkali metals (Li, Na, K, Rb, Cs) and halogen (F, Cl, Br, I, At). Simulations based on density‐functional theory are used to study the electronic and optical properties
