| Abstract: | The occurrence of unusual electronic, magnetic and optical properties displayed at the nanoscale provides an incentive to explore innovative routes to nanosynthesis. The nanoporous structure of anodized alumina is a convenient template for self-assembly of nanowires using simple beaker chemistry. In our laboratory, we routinely self-assemble extremely well regimented arrays of metallic and semiconductor nanowires (e.g. CdS, ZnSe, Cu, Ni, Fe, Co) of diameter 10 nm or 50 nm using anodized alumina templates. By depositing aluminum on a substrate of choice (e.g. silicon) and subsequently anodizing it, one can obtain the porous structure on a sturdy substrate. Nanowires are then produced by filling the pores with the material of interest. This is an inexpensive nanosynthesis technique that produces device quality materials with high throughput. | |
