Carbon nanotube field-effect transistors - An example of an ultra-thin body Schottky barrier device

We present experimental and simulation results on carbon nanotube field-effect transistors (CNFETs) and discuss their performance in the context of Schottky barriers in a strongly confined geometry. We focus in particular on the impact of the body thickness-the tube diameter-and explain why conventional output characteristics can be obtained in case of CNFETs.
