The p-ZnO and the ZnO p-n homojunctions on n-Si(110) were grown by the methods of RF and DC reaction magnetron sputtering. An oxygen rich condition has been kept in growing process of the p-ZnO. The FWHM of the ZnO (002) diffraction peaks are 0.3° obtained by XRD measurements. A hexagonal self-assembled structure of the ZnO films is shown by atomic force microscopy. The 390 nm UV emission peak of the ZnO films present in the cathodoluminescence spectra. The
I-V
property of the ZnO p-n junction was measured by an
I-V
character. The curve indicates a value of 1.1 volts forward threshold
which is equal to the results of the ZnO p-n junction grown in Japan and America using DC sputtering method and diffusion method; meanwhile the backward characteristics of our sample is much better.
