Abstract:

One-dimensional (1D) aligned ZnO nanowire arrays with different morphologies were synthesized by a solution-phase method. The morphology and microstructure of the products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The field emission property of different ZnO nanowire array samples was compared. The factors that influence the field emission property of the 1DZnOnanowire arrays were analyzed using the Fowler-Nordheimequation. The results showed that the ZnOnanowire samples with the lower areal density, higher aspect ratio, and thin tips showed much better field emission characteristics.
