Patent ID: 7786466

Claim:
A semiconductor structure comprising: a first semiconductor device including a first gate electrode located over a first region of a semiconducting carbon nanotube and not directly contacting said first region, wherein said semiconducting carbon nanotube is located on a substrate, wherein charge carriers in said first region are predominantly holes; a second semiconductor device including a second gate electrode located over a second region located in said semiconducting carbon nanotube and not directly contacting said second region, wherein charge carriers in said second region are predominantly electrons; and a laterally abutting pair of a third region and a fourth region of said semiconducting carbon nanotube, wherein said laterally abutting pair is located in said semiconducting carbon nanotube, wherein charge carriers are predominantly electrons in said third region and predominantly holes in said fourth region, and wherein said third region laterally abuts said first region and said fourth region laterally abuts said second region.
