摘要
The first-principles with pseudopotentials method based on the density functional theory was applied to calculate the electronic structure of ZnO doped with carbon. It optimized the wurtzite structure of ZnO when carbon was on the substitutional O site (C-O), the substitutional Zn site (C-Zn) or in the interstitial site (C-i) respectively. The calculated conclusions show that the C-Zn and C-i behave as donor. However, C-O results in acceptor. It is illuminated that C-O is helpful to achieve p-type ZnO.
