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...

This error sometimes arises when two models which are declared in the command files are contradicting each other.

One of the possible solutions is to increase the mesh density in the interface region.

The second is to tune the min step, max step, and increment.

Okay, thanks will try that, also I am facing an error that interface "region_1/region_2" is not found in the grid file, is meshing at that interface a solution to this?
