摘要	Effects of magnesium on phosphorus chemical states and p-type conduction behavior of phosphorus-doped ZnO (ZnO:P) films were investigated by combining experiment with first-principles calculation. Photoluminescence (PL) spectra show that Mg incorporation increases the amount of VZn, which makes more PZn-2VZn complex acceptor formed and background electron density decreased, leading to that MgZnO:P exhibits better p-type conductivity than ZnO:P. The p-type conductivity mainly arises from P Zn-2VZn complex acceptor with a shallow acceptor energy of 108 meV. X-ray photoelectron spectroscopy (XPS) spectra reveal that phosphorus has two chemical states of PZn-2VZn complex and isolated PZn, with binding energy of P2p3/2 of 132.81 and 133.87 eV, respectively. The conversion of isolated PZn to P Zn-2VZn complex induced by Mg incorporation is observed in XPS, in agreement with the PL results. First-principles calculations suggest that the formation energy of nMgZn-VZn complex decreases with the increasing Mg content, well supporting the experiments from the PL spectra and XPS measurements. 2013 American Institute of Physics.
