ZnO nanowires were synthesized by hydrothermal method using Au nanodots on Al doped ZnO (AZO) seed layer to control those density and morphology. Morphology of the synthesized ZnO nanowires could be modified effectively by controlling the feature of Au nanodots obtained from the thickness and post thermal treatment conditions of Au thin films prepared on AZO seed layer. The synthesized ZnO nanowires showed vertically grown features and long length despite relatively short synthesis time, while their density could be controlled effectively by the technique proposed in this study. In particular, the ZnO nanowires synthesized on Au nanodots formed after thermal treatment at 700 °C showed outstanding length and distinctively decreased density.
