One of the main areas in the field of nanotechnology is fabricating nanostructures and nanodevices as well as measuring and manipulating them. A particular emphasis has been placed on the fabrication of meso/microscopic systems, which enable us to explore the exotic physical phenomena in the deep sub-micron region. Typical fabrication of nanostructures with various shapes and dimensions has been performed by the conventional electron beam lithography. Recently many of research efforts have been focused on developing template-based fabrication techniques such as nano-imprint technique, which enables parallel processes. Among these newly emerging techniques, anodized aluminium oxide (AAO) has been gained much interest due to the formation of a porous structure. Since the array of pores on the surface of AAO is highly ordered with a high pore density, and the dimensions of the porous structure such as the size of the pores and the separation between them can be easily varied by controlling the anodization conditions, AAO can be favorably employed as a template for the nanostructure fabrication. In addition, one of advantages using AAO is that the porous substrate can be easily prepared using a rather simple anodization method. At Applied NanoPhysics Lab, we would like to explore the possibility of fabrication of nanostructures based on AAO template.
