Patent ID: 8350360

Claim:
A carbon nanotube capacitor, comprising: a carbon nanotube film; a substrate disposed below the carbon nanotube film; a first end electrode disposed at a first end of the carbon nanotube film, wherein the first end electrode comprises an upper first end electrode disposed above the substrate and a lower first end electrode disposed in the substrate, and wherein the upper first end electrode and the lower first end electrode are connected; a second end electrode disposed at a second end of the carbon nanotube film, wherein the second end electrode comprises an upper second end electrode disposed above the substrate and a lower second end electrode disposed in the substrate, and wherein the upper second end electrode and the lower second end electrode are connected; an upper electrode disposed above the carbon nanotube film and in a middle region of the carbon nanotube film; and a lower electrode disposed below the carbon nanotube film and in the middle region of the carbon nanotube film, wherein the lower electrode is disposed within the substrate, wherein the substrate comprises a lower dielectric layer disposed below the carbon nanotube film, between the lower first end electrode and the lower electrode, and between the lower second end electrode and the lower electrode, wherein the first end electrode is different from the second end electrode, the upper electrode and the lower electrode, wherein the second end electrode is different from the upper electrode and the lower electrode, wherein the upper electrode is different from the lower electrode, and wherein the carbon nanotube capacitor is a four terminal device comprising four terminals, wherein a first one of the four terminals is the first end electrode, a second one of the four terminals is the second end electrode, a third one of the four terminals is the upper electrode, and the fourth one of the four terminals is the lower electrode.
