Abstract
A method of fabricating a tunneling nanotube field effect transistor includes forming in a nanotube an n-doped region and a p-doped region which are separated by an undoped channel region of the transistor. Electrical contacts are provided for the doped regions and a gate electrode that is formed upon a gate dielectric layer deposited on at least a portion of the channel region of the transistor.
