Abstract

CdS is a potential candidate for material in optoelectronic applications. The magnetic, electronic and optical properties of Ag- doped and Co -codoped CdS were calculated using full potential linear augmented plane wave (FP-LAPW) based on popular density – functional theory (DFT). The band gap and density of states for Ag -doped and Cocodoped CdS have been determined by using Tran Blaha modified Becke-Johnson (TBmBJ) potential. The optical and electronic properties of Ag-doped and Co-codoped CdS such as absorption coefficient, energy loss function, reflectivity, refractive index, electrical conductivity and extinction coefficient are presented. The results indicate that the magnetic and electro-optical properties are improved by this doping.
