  • Carbon nanotube field effect transistor
    Patent number: 7714386
    Abstract: A carbon nanotube field effect transistor includes a substrate, a source electrode, a drain electrode and a carbon nanotube. The carbon nanotube forms a channel between the source electrode and the drain electrode. The carbon nanotube field effect transistor also includes a gate dielectric and a gate electrode. The gate electrode is separated from the carbon nanotube by the gate dielectric, and an input radio frequency voltage is applied to the gate electrode.
    Type: Grant
    Filed: June 9, 2006
    Date of Patent: May 11, 2010
    Assignee: Northrop Grumman Systems Corporation
    Inventors: Aaron Anthony Pesetski, Hong Zhang, John Douglas Adam, John Przybysz, Jim Murduck, Norman Goldstein, James Baumgardner
