US Patent 7579618 - Carbon nanotube resonator transistor

This patent from Northrop Grumman teaches a mechanically resonant carbon nanotube transistor providing a low output impedance in comparison to other CNT designs and a high operating frequency suitable for signal processing applications. Claim 1 reads:

1. A resonant transistor comprising:

a substrate;

a source formed on said substrate;

a drain formed on said substrate adjacent to said source,

a gap being formed between said source and said drain;

an input electrode formed on said substrate; and

a carbon nanotube gate positioned over said gap and over said input electrode, said nanotube gate being clamped on one end by a contact electrode.
