Carbon Nanotube Transistors: an Evaluation
نویسندگان
چکیده
A simple, non-equilibrium model is used to evaluate the likely DC performance of carbon nanotube field-effect transistors. It is shown that, by appropriate work function engineering of the source, drain and gate contacts to the device, the following desirable properties should be realizable: a sub-threshold slope close to the thermionic limit; a conductance close to the interfacial limit; an ON/OFF ratio of around 10; ON current and transconductance close to the low-quantum-capacitance limit.

Application of Neural Space Mapping for Modeling Ballistic Carbon Nanotube Transistors
In this paper, using the neural space mapping (NSM) concept, we present a SPICE-compatible modeling technique to modify the conventional MOSFET equations, to be suitable for ballistic carbon nanotube transistors (CNTTs). We used the NSM concept in order to correct conventional MOSFET equations so that they could be used for carbon nanotube transistors. To demonstrate the accuracy of our mod...
