Abstract:
1. A method of fabricating a nanotube field effect transistor, comprising: (a) providing a back gate layer; (b) forming a gate dielectric layer on the back gate layer; (c) forming a local gate electrode and an insulating layer on the gate dielectric layer; (d) forming a nanotube on the insulating layer and the gate dielectric layer, where said nanotube has a central region disposed on the insulating layer and a first end and a second end disposed on the gate dielectric layer; (e) forming a source electrode on the first end of the nanotube, where the source electrode is separated from the central region by a first region of the nanotube; (f) forming a drain electrode on the second end of the nanotube, where the drain electrode is separated from the central region by a second region of the nanotube; and (g) doping the nanotube in the first region and in the second region.
