Although nitrogen-doped zinc oxide has been fabricated as a light-emitting diode, the origin of its p-type conductivity remains mysterious. Here, by analyzing surface reaction pathway N in ZnO with first-principles density functional theory calculations, we demonstrate that N-doped can originate from defect complexes N(Zn)-V(O) and N(O)-V(Zn). Favored Zn-polar growth, shallow acceptor N(O)-V(Zn) actually evolves double-donor state N(Zn)-V(O). While is metastable, p-doping mechanism...
