Can carbon nanotube transistors be scaled without performance degradation?

The effects of channel length scaling on carbon nanotube field-effect transistor (CNTFET) performance was investigated by varying device lengths on the same nanotube. Results show that scaling improves performance with substantial increases in on-current, resistances closer to the quantum limit than have ever been reported, and the shortest (∼30 nm) well-behaving CNTFETs to date. © 2009 IEEE.
