Claim Text:
1. A carbon nanotube transistor, comprising: a carbon nanotubes on a substrate; a gate structure deposited on the carbon nanotube, wherein the gate structure include a layer of first dielectric material for doping the carbon nanotube at the gate structure; a source electrode deposited on one end of the carbon nanotube and separated from the gate electrode by a first gap; a drain electrode deposited on an opposite end of the carbon nanotube and separated from the gate electrode by a second gap; a layer of second dielectric material formed in the first gap for doping the carbon nanotube in the first gap, wherein the second dielectric material is different from the first dielectric material; and a layer of the second dielectric material formed in the second gap for doping the carbon nanotube in the second gap; wherein the doped carbon nanotube forms a p-n junction at a transition between the gate structure and the first gap and at a transition between the gate structure and the second gap.
