Abstract: Carbon nanotubes based FET devices are getting more importance today because of their high channel mobility and improved gate capacitance versus voltage characteristics. This discussion provides an overview of carbon nanotubes, Operation of CNTFET, current types of CNTFETs, V-I characteristics of CNTFET, and comparison of type of CNTFET on different design parameters.
Keywords: Ballistic transport, carbon nanotubes (CNTs), non-equilibrium Green’s function (NEGF), technology computer aided design (CAD).
