While trying to do the simulation of the gan hemt on tcad sentaurus, do we need to fit the mobility with the given hall mobility in the experiment ?

do we need to change the GaN material mobility in tcad with the hall mobility in the experimental paper? and do we need to match the sheet charge density too? Is this sheet charge density...

I am trying to simulation a double channel hemt on Sentaurus TCAD but Transferred Electron 2 model is not working? Can anyone help to understand ?

The mobility model that I am using is DopingDependence model and Transferredelectrton2 for high field degradation of mobility by intervalley scattering. This should reduce the current but it is...
