Abstract:
1. A method for fabricating a rotary device, comprising: providing a multiwall nanotube in a well formed through a top sacrificial layer and into a bottom silicon layer of a silicon-insulator-silicon layered substrate having the top sacrificial layer deposited thereon; forming a first release region around a first portion of the multiwall nanotube, rotor material over the first release region and around a second portion of the multiwall nanotube, a second release region over the rotor material and around a third portion of the multiwall nanotube, and a support structure over the second release region and around a fourth portion of the multiwall nanotube; and removing the sacrificial layer, the insulator layer, the first release region, and the second release region so as to space the rotor from the support structure and the bottom silicon layer, but such that the rotor remains coupled to the multiwall nanotube and is free to rotate about a long axis of the multiwall nanotube.
