    摘要: A method is provided for forming a device. The method provides an insulating substrate including a source electrode, a drain electrode, and a gate electrode. The method provides carbon nanotube bundles including metallic and semiconducting component nanotubes in contact with the substrate. The method applies a voltage to the gate electrode to deplete the semiconducting component nanotubes of carriers, applies an electrical current through the nanotube, from a source electrode to a drain electrode, and breaks at least one metallic component nanotube to form a field effect transistor. The carbon nanotube bundle can be a multi-walled nanotube or a single-walled nanotube rope.

    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.
