Abstract:
1. A semiconductor device, comprising: a substrate; source and drain conductors on the substrate; a semiconducting carbon nanotube interconnecting the source and the drain conductors, the semiconducting carbon nanotube, in at least one cross-section transverse through an elongate axis of the semiconducting carbon nanotube, having opposing sides; a plurality of gate dielectric portions, each gate dielectric portion being adjacent to one of the opposing sides of the semiconducting carbon nanotube; a catalyst deposited on a surface of one of the gate dielectric portions adjacent to the semiconducting carbon nanotube; and a plurality of gate electrodes, in the cross-section, being electrically disconnected from one another, at least one gate electrode being adjacent to each of the gate dielectric portions, the gate electrodes located such that when a voltage is applied to the gate electrodes, the source and the drain conductors are electrically coupled through the semiconducting carbon nanotube.
