Abstract:One-dimensional (1D) aligned ZnO nanowire arrays with different morphologies were synthesized by a solution-phase method. The morphology and microstmcture 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 1D ZnO nanowire arrays were analyzed using the Fowler-Nordheim equation. The results showed that the ZnO nanowire samples with the lower areal density, higher aspect ratio, and thin tips showed much better field emission characteristics.
Keywords:ZnO  ZnO  Nanowire array  Field emission  Solution-phase method
