There are no such thing u have asked about. Each nano material could have different properties based on size, dimensions, average particle size distribution, or even the synthesis technique and used material impurity grad. Therefore, you can just do focus in a specific material. Moreover, you mentioned FET, which could presented in different structure through the using of conductor, insulator and semiconductor. The nano material could be one of those or all of them, which makes the question blow your mind... Define your needs at first.

Abd Elhamid Mohamed Abd Elhamid Thank you for your reply... I understand that I should fix a material first.. Then I have question - without considering the material we use, what are the parameters that the overall performance of the FET depend upon?

Dear Dr. Harith Gurunarayanan

The most used parameters to study and investigate the performance of FETs (Organic FETs, SOI MOSFETs, Carbon Nanotube FETs...) are the channel length of nano-transistor and the Electron mobility.

I recommend a few articles:

(my recent work about the thermal stability of Graphene FETs (GFETs)

https://www.nature.com/articles/nnano.2014.207

(about the affects of channel length of nano-transistor and the Electron mobility. For long-term (2026) the small channel transistor is estimated to be of the order of 5.8 to 5.9 nm)

The answer will based upon two main parameters namely; gate dimensions and semiconductor properties. The superior fictionalization f nano materials over bulk one is focused in the semiconductor epic features than the bulk such as carrier concentration and draft velocity.
