Optical Characteristics of Cadmium Oxide and Magnesium Doped with Nanoclusters

The optical characteristics of cadmium oxide and Magnesium (Mg) doped with nanocluster structures were studied using a computational simulation method based on density functional theory. The CASTEP package was used to make the calculations using the local density approximation. The optical bandgap energy increased from 1.544 to 2.896 eV with Mg doping increased. Furthermore, optical results showed that reflectivity, absorption and conductivity of the cluster system structures varied from (400–800 nm) range with doping.
