Abstract:
1. The nanotube array ballistic transistor, comprised of the following components: dielectric substrate; first conducting electrode, the cathode, deposited on said substrate; array of carbon nanotubes grown on said first conducting electrode normally to the substrate plane; dielectric film covering said carbon nanotubes, said dielectric film being thinner than the height of said carbon nanotubes, so that after deposition of said dielectric film the ends of said carbon nanotubes protrude beyond said dielectric film; thin metal layer deposited on the exposed nanotube tips, said nanotube tips becoming exposed after polishing the surface of said second dielectric film and thus removing protruded nanotube ends; second conductive electrode, the gate, deposited on said dielectric film aside from said nanotube tips and in electrical contact with said thin metal layer; third conducting electrode, the anode, deposited on said dielectric film, aside from both said nanotube tips and said second conductive electrode, device housing made over said ballistic transistor to provide vacuum in the device active volume.
