川超绵阳VS乐山

The first principles calculation of plane wave ultra-soft pseu-dopotential method based upon the denstiy functional theory and generalized gradient approximation have been adopted to investigate the energy band structure and electronic density of states and Mulilken charge population of Al and N codoped Zn1-xMgxO. The calculation indicates that the Al and N codoped Zn1-xMgxO has the trend of forming p-type Zn1-xMgxO.
