Abstract:
1. An electrostatically-doped carbon nanotube device, comprising: a carbon nanotube disposed on a substrate such that at least a portion of the carbon nanotube is free-standing, wherein said carbon nanotube has a first end and a second end; a first metal contact disposed directly adjacent to the first end of the carbon nanotube; a second metal contact disposed directly adjacent to the second end of the carbon nanotube, wherein said carbon nanotube is electrically coupled to the first and second metal contacts; a first metal electrode disposed in the substrate adjacent to and at a distance from the first end of the carbon nanotube, wherein the first metal electrode is capacitively coupled to the first end of the carbon nanotube and is operable for receiving a first bias to electrostatically dope the first end of the carbon nanotube; and a second metal electrode disposed in the substrate adjacent to and at a distance from the second end of the carbon nanotube, wherein the second metal electrode is capacitively coupled to the second end of the carbon nanotube and is operable for receiving a second bias to electrostatically dope the second end of the carbon nanotube.
