There would be Schottky Barriers at source and drain which have to be modelled. Which Physics Models in Sentaurus TCAD should be used to correctly model RFETs and also how to code the parameter file for the same?
Dear Mohit,
What do you mean by RFET? Do you mean Ribbon FET?
Any way, there exist many of such layered and nanotubes structures, some have Schottky Barriers at source and drain and some have one ohmic and one Schooky and some have both ohmic, depending on the doping of source and drain sides of the channel region.
In all cases, you'd choose the suitable simulator for your device (Quantum or semiclassic)
I recommend using Micro-Cap (http://www.spectrum-soft.com/download/download.shtm). All EE's at Emerson used Micro-cap, even though it cost $4,000 each. There are no other electronic SPICE modeling programs even close to Micro-Cap capability.
Micro-Cap is now free. Andy Thompson, owner of Spectrum Software, has retired.
Micro-Cap does worst case analysis --- changing the tolerances of components --- changing the temperature --- etc. And it is easy to use.
I have used Micro-Cap for all of my electronic designs since 2001. When I tested prototypes, they worked exactly as the model predicted.
The website --- https://NDAcademy.FoxPing.com/ --- 2.8 Electronic Cascade RC Filters --- and --- 7.2 Electronic SPICE Models --- provide examples.
