摘要：
We carried out a nitrogen plasma treatment process to obtain N-doped ZnO single crystal. The treated sample showed an acceptor related emission located at 3.354 eV when excited by a 325-nm He-Cd laser at 85 K. Raman spectra revealed the formation of a bond between Zn and N atoms. The surface work function indicated increasing of hole concentration of the N-plasma-treated ZnO. By constructing a ZnO-based homojunction, the I-V curve displayed perfect rectification performance.
