Abstract:
1. A method of producing a nanostructure comprising an anodized film including a nanohole on a substrate having a surface containing at least one material selected from the group consisting of semiconductors, noble metals, Mn, Fe, Co, Ni, Cu and carbon, the nanohole passing through the anodized film from the surface of the anodized film to the surface of the substrate, said method comprising the steps of: (i) forming a film including aluminum on the substrate having a surface containing at least one material selected from the group consisting of semiconductors, noble metals, Mn, Fe, Co, Ni, Cu and carbon; and (ii) anodizing the film including aluminum, wherein in step (ii) the anodizing is conducted while monitoring an anodization current and the anodizing of the film including aluminum terminates after a reduction in the anodization current from a steady-state value is detected.
