Abstract

The progression of nanostructures and nanodevices from the R&D lab to manufacturing environments is the next great challenge that must be met if these devices are to become commercially viable. This project deals with fabricating nanoporous metal oxide templates whose pores are controllable in size, separation and spatial uniformity over large areas and filling the pores to fabricate devices inside them. These templates can be filled with (i) semiconductors to fabricate heterojunction devices, (ii) magnetic materials for nanowire based recording applications, and (iii) carbon nanotubes for nanoelectronic devices and sensor applications. These membranes can also be used in fluid flow and filtration applications, DNA separation and drug delivery. We have been successful in fabricating nanowire/nanotube based devices using alumina templates.
