Abstract
The ZnO (0001) and (0001̄) surfaces irradiated with nitrogen using an electron cyclotron resonance (ECR) gun were studied with X-ray photoelectron spectroscopy (XPS). After annealed at 800°C, N ions remained on the surfaces in four states: i.e. NO, N2, the N species that has excess electrons like NH3 or N2, and the N ions that replaced O ions in ZnO lattice. The surface oxygen could be substituted with N ions that could affect N-doping and the heterogeneous growth of nitride thin films on ZnO.
