Field emission properties of ZnO nanorod arrays by few seed layers assisted growth
چکیده انگلیسی
ZnO nanorod arrays growth on few seed layers was synthesized using a simple two-step process with sol-gel and hydrothermal methods. The effect of seed layers on structure, energy band, and field emission properties of ZnO nanorods has been studied. The ZnO nanorod arrays grown on the 4 layer shows larger density and better vertical orientation. The PL spectra of the ZnO nanorod arrays grown on different numbers of seed layer also were studied. The intensity ratios of the 4 seed layer and ZnO nanorod array grown on 4 seed layer show the largest values, which indicates that there are the most intrinsic defects in the sample. The defects may provide better conductivity. The ZnO nanorod array grown on the 4 layers possesses better field emission property.
