Abstract
An example of a carbon nanotube capacitor may include (i) a carbon nanotube film having carbon nanotubes and voids with dielectric material, (ii) conductive contacts and (iii) a dielectric layer. The carbon nanotube film may switch from a conductive state to a non-conductive state when a voltage is applied by creating an electrical break within the carbon nanotube film and providing a first conductive region and a second conductive region within the carbon nanotube film. The electrical break may separate the first conductive region from the second conductive region. The first and second conductive regions may store charge. An integrated device may include one or more transistors and one or more carbon nanotube capacitors. A method of making a carbon nanotube capacitor is also disclosed.
