This work aims to investigate the phenomena of Schottky barrier between Au/TiO2 nanotubes. The microstructure and surface morphologies of TiO2 nanotubes were characterized by XRD, SEM and XPS. Micro-layers of Au were deposited on TiO2 nanotubes surface by thermal evaporation. The two electronic probes were employed to confirm Schottky contact barrier between Au/TiO2 interface. The IV characteristic curves can be explained by the energy band diagram.
