how to consider the effect of scattering on the performance of 2D FETs

[dong0216]

Dear all,
I want to konw how to consider the effect of scattering (such asinterfacial Coulomb scattering ) on the performance of the short-channel field effect transistors based on 2D monolayer semiconductors in the QuantumATK software?
Thank you.

Basically all these kinds of scattering effects come from the geometry, i.e. which atoms are located where. So, all you need to do is add extra atoms, same thing to model edge roughness of a nanoribbon, holes in the 2D sheet, etc.
