摘要	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 the surface reaction pathway of N in ZnO with first-principles density functional theory calculations, we demonstrate that the origin of p-type conductivity of N-doped ZnO can originate from the defect complexes of N Zn-VO and NO-VZn. Favored by the Zn-polar growth, the shallow acceptor of NO-VZn actually evolves from the double-donor state of NZn-VO. While NZn-VO is metastable, the p-doping mechanism of N Zn-VO&rarrNO-VZn in ZnO will be free from the spontaneous compensation from the intrinsic donors. The results may offer clearer strategies for doping ZnO p-type more efficiently with N. 2012 American Physical Society.
