Theoretical study of electronic properties of Zn1−x(TM)xO (TM=Mg,Cd)

The paper present study of the electronic and optical properties of Zn1-x(TM)x (TM=Mg,Cd), through density function theory (DFT) based on first-principles method. The calculation indicate that the band gap of Zn1-xCdxO narrows as result of the increasing concentrations of Cd. The paper shows that th...

Summary:The paper present study of the electronic and optical properties of Zn1-x(TM)x (TM=Mg,Cd), through density function theory (DFT) based on first-principles method. The calculation indicate that the band gap of Zn1-xCdxO narrows as result of the increasing concentrations of Cd. The paper shows that the Zn 4s and Cd 5s electron states broadens to low energy states and that the O2p electron states broadens to high energy states with increasing Cd-doping concentrations. The paper advances a possible theoretical mechanism of Cd-doped regulating Bands gap. Optical property of Zn1-x(TM)x (TM=Mg,Cd) is presented in the paper.
