http://www.freepatentsonline.com/7692249.html

This patent from Intel (priority 1/24/2004) includes some basic claims covering carbon nanotube transistors formed using chemical self-assembly. Claim 1 reads:

1. A transistor comprising:

a source region;

a drain region;

a plurality of nanotubes extending between said source and drain regions, said nanotubes having functionalized ends with attached functional groups, wherein said nanotubes have opposed first functionalized ends coupled to said source region and second functionalized ends coupled to said drain region, said first functionalized ends attracted to said source region and not said drain region; and

a gate electrode over said nanotubes.
