I am trying to simulate traps in TFET interfaces between oxide and silicon using sentaurus Sdevice. I included the traps in command file as follow:
Physics (MaterialInterface = "Silicon/HfO2") {
Traps( hNeutral Uniform EnergyMid = 0.22 EnergySig=0.02 Conc = 1e13 eJfactor = 0 eJfactor = 0 TrapVolume = 1e-11 HuangRhys = 3 PhononEnergy = 0.06 )
}
and include the parameter as follow:
MaterialInterface = "Silicon/HfO2" {
Traps{
Vth = 7.57e7 , 7.57e7
Xsec = 1e-15 , 1e-15
}
}
But the following error appear :
Unable to save dataset 'TrapOccupation_0(hN,Un)':
interface 'gateoxide2/channelregion' not found in grid file sdemodel_msh.tdr !
How could I fix this problem???
Thank you, but I follow this link to model the trap and the error still existing
The error seems that the interface is not formed in the structure file.
If it does not help, I would prefer to use the command "regioninterface", instead of materialinterface. Or you first reduce the number of commands of the trap.
Best regards,

Hi, I guess this issue might be already solved, but the answer is not updated.
Since I just came across and solved this issue. I'd like to share a possible solution.
The problem here can be missing definition of interface regions in the TDR file which will be used for device simulation.
In my case, I was using SDE+SnMesh to create structure (because the sprocess defines the interface region, so don't need to consider). One can create a "shell" tool to run the preprocessed SnMesh command file (in case there are variables defined in the tree) while specifying the option "-AI" in the command line.
Then the interface regions will be added to the TDR.
