摘要:
A method of fabricating a nanotube field-effect transistor having unipolar characteristics and a small inverse sub-threshold slope includes forming a local gate electrode beneath the nanotube between drain and source electrodes of the transistor and doping portions of the nanotube. In a further embodiment, the method includes forming at least one trench in the gate dielectric (e.g., a back gate dielectric) and back gate adjacent to the local gate electrode. Another aspect of the invention is a nanotube field-effect transistor fabricated using such a method.

The method includes forming a 1-10000 nm thick SiO2, HfO2, Al2O3 and/or quartz gate dielectric on an Si back gate. An Al or Mo gate electrode is formed on the gate dielectric. An Al2O3 insulating layer is formed over the gate electrode. A C, Si, GaAs, InP, and/or InGaAs nanotube is formed on the insulating layer and gate dielectric. The nanotube has a central region on the insulating layer above the gate electrode and first and second ends on the gate dielectric. A source is formed on the first end and spaced from the central region and gate electrode by a first peripheral region. A drain is formed on the second end and spaced from the central region and gate electrode by a second peripheral region. The first and second peripheral regions are doped with Cl2, Br2, K, Na, or a molecule of polyethylenimine using wet deposition or evaporation.
