Abstract:
1. A carbon nanotube field effect transistor comprising: a semiconductor substrate; at least one carbon nanotube above said substrate, said carbon nanotube having a first side, a second side opposite said first side and opposing ends, and comprising a channel region between said opposing ends; source/drain electrodes contacting said opposing ends on said first side without extending laterally beyond said opposing ends; a first gate on said first side above said channel region, said first gate being positioned laterally between said source/drain electrodes such that no portion of said first gate overlaps said source/drain electrodes, wherein said first gate is adapted to impart a first potential on said channel region so as to turn on said carbon nanotube field effect transistor; and second gates between said second side and said substrate, said second gates being positioned adjacent to said opposing ends opposite said source/drain electrodes,
