This article is from Nanoscale Research Letters, volume 9.AbstractIn this work, we have demonstrated that amorphous ZnO nanobranches a-ZnO NBs could spontaneously react from the crystalline ZnO NWs c-ZnO NWs at specific humid environment. The spontaneous reaction mechanism and result can be analyzed by humidity controlling and optical microscope OM-scanning electron microscope SEM-Kelvin probe force microscopy KPFM-transmission electron microscopy TEM system. We can make the c-ZnO NWs spontaneous reaction happen at different humid environments and suppress the a-ZnO NBs spontaneous reaction by oxygen-hydrogen plasma surface passivation. The hydrogen plasma surface treatment also can improve the UV sensing sensitivity more than twofold. This work provides the mechanism and methods of the a-ZnO NBs spontaneous growth and offers the passivation treatment for strengthening and enhancing ZnO-based nanodevice application in humid environment and UV light detection, respectively.
