Paper Abstract

A nanoporous alumina template made from a multilayer metal film structure has been developed that allows for the in situ removal of the electrically insulating alumina barrier layer, exposing a Pt electrode at the pore bases. This barrier free nanoporous system has great potential for DC electrodeposition of a wide variety of materials in the alumina pores. The nanoporous template is fabricated in a more practical way than existing techniques and can be used for the fabrication of nanowires of many materials. Because the template is fabricated directly on the final substrate, no film transfer technique is needed and the substrate can include electrical circuitry. A silicon substrate may be used that provides mechanical stability, facilitates processing, and allows integration with IC components. This will allow for cheap and high efficiency infrared detectors to be fabricated in a practical and cost effective way. The quantum wire devices fabricated in this way can be customized to be used as infrared sensors at a variety of infrared wavelengths.
