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...

I am simulating a GaN HEMT on Sentaurus TCAD, I am facing a error as RHS value is exceeding 1e20. Can someone please tell as how to remove the issue?

min step=1e-3 max step=0.01 minstep=1e-5 increment =1.55 , models is hydrodynamic, math i have tried with default and also blocked and pardiso

I am trying to take a FFT of a transient response ( sin wave) on ATLAS (SILVACVO) but I am not a getting a proper DC offset value?

I am changing the fundamental frequency and the maximum harmonic value and the dc offset is coming different every time. how do I set the accurate parameters?

How to the solve convergence problem with the Q factor in quantum model while using it in GaN HEMT(Silvaco ATLAS) ?

solve qfactor=0.0001 solve qfactor=0.0005 solve qfactor=0.004 solve qfactor=0.02 solve qfactor=0.1 solve qfactor=1.0 trying out all the combinations but still convergence issues
