To fabricate TiO2 1D and 2D nanostructures easily and reproducibly, surface relief gratings (SRGs) on azobenzene-functionalized polymer films were used as templates in the process of sol-gel reaction of Ti precusor. In a one-step process of exposure to an appropriate interference pattern of light, sinusoidal SRGs could be formed on azobenzene-functionalized polymer films as the result of mass transport of the polymer chain. Successful preparation of TiO2 nanostructures was confirmed by the AFM and SEM measurements. Further applications of these structures to the fabrication of solar cell and the patterning of transparent conducting oxide layer which could be used as the electrodes in the fabrication of devices such as light-emitting diodes, solar cells, electrochromic devices, and thin film transistors were performed. |
