I am using Silvaco Atlas and trying to simulate AlGaN/GaN HEMT structure including tunneling model. I am using qtregion for defining tunneling region and meshing of 1 A in that region. The voltage steps used is 0.01V. I am repeatedly getting the error : "Error : Code 2 in GetTransmissionProbability function of CTunnelCurrent".
If anyone have worked with tunneling model in Silvaco Atlas. Kindly help
Hi Dear Upadhay,
I also encountered a similar error in simulating a commom 2 gate tunneling FET.
Ofcourse, the program ignores the error and end running that, but, the current chracteristics of the device is not true (it is about zero for all variations in gate voltage).
Could you solve your problem?
Please advice me.
Best Regards.
While simulating the quantum tunneling, you should specify qtx and qty with reference to the gate electrode. If you take the reference as source (since tunneling occurs from source to channel) you will face the problem of Error - Code 2 in GetTransmissionProbability function of CTunnelCurrent". Check this in your code.
All the best.
