Electrodeposition of Nanowires and Nanostructures from Supercritical Fluids
In order to explore the possibilities of using electrodeposition from supercritical fluids to make sub 20 nm nanostructures and nanostructured devices we have focused on the electrodeposition of a range of p-block elements (Ga, In, Ge, Sn, Pb, Sb, Bi, Se and Te) from supercritical difluoromethane . In this lecture I will present results of our latest results on electrodeposition of these elements from supercritical difluoromenthane, the characterization of the electrodeposited materials, and work on the electrodeposition of sub-20 nm nanowires. I will discuss the experimental systems and novel reagents required to undertake this work, including the development of a simple high pressure, high temperature electrical feedthrough. I will also discuss our progress towards making transistors from supercritical fluid electrodeposited nanowires.
