Abstract
In this work, the electronic, magnetic and optical features of the diluted magnetic semiconductors (DMS) Cd1-xFexS (x= 6.25%, 12.5%, 25%) are determined by density functional theory (DFT). The analysis of electronic BS and magnetic moment of Cd1-xFexS show a half metallic ferromagnetic (HMF) nature with direct energy gap (E-g).The E(g)of CdS is elevated by incrementing the doping concentration of iron atoms. Moreover, the replacement of Cd with Fe turns CdS into an-type semiconductor. The effect of Fe concentration on the optical parameters such as absorption coefficient, refractive index, dielectric function, optical conductivity, and reflectivity is also investigated. Results revealed that Cd1-xFexS is a suitable compound for spintronicsand optoelectronics devices.
