| 20100032653 | Carbon Nanotube Electric Field Effect Transistor and Process for Producing the Same - This invention provides a process for producing a carbon nanotube electric field effect transistor that can improve yield in channel preparation. Carbon nanotubes dispersed in a mixed acid composed of sulfuric acid and nitric acid are subjected to radical treatment with aqueous hydrogen peroxide to cut the carbon nanotubes and thus to provide carboxyl-introduced carbon nanotube fragments. The carbon nanotube fragments are attached, through a covalent bond and/or an electrostatic bond, to a site, where a source electrode is to be formed, and a site where a drain electrode is to be formed, in a substrate with a functional group, to be attached to a carboxyl group, introduced thereinto. The carbon nanotube fragments attached to the substrate are attached to carbon nanotubes as channels through n-n interaction to fix the carbon nanotubes as channels to the substrate. | 02-11-2010 |
