Carbon Nanotube FET: Gate Voltage and Conductance

[w.shockley]

i don't understand how an applied Voltage on a (intrinsic) Carbon Nanotube could change its conductance... There is not a population inversion like in mosfet. So, which is the physics? Where this carriers can from?

thank you.

It's called Coulomb Blockade. Pure electrostatic interaction with the carriers.
