Rapid Hydrothermal Synthesis of Zinc Oxide Nanowires by Annealing Methods on Seed Layers

Figure 1

AFM images of the ZnO seed layers with annealing (a) in air, (c) in N₂, and (e) in a vacuum; SEM micrographs of the ZnO nanowire arrays under three different seed layer annealing conditions: (b) air, (d) N₂, and (f) vacuum. The insets show the cross-sectional view of the ZnO nanowire arrays.
