Hi , i am tring to simulate CNTFET in silvaco atlas ,but when i want to have self-heating effect i use lat.temp model give me an error :
Error: No default thermal conductivity model for material CMO.
Please specify model
what do ia have to do?

Isn't the error message clear?
Your material CMO does not have certain material properties defined - thermal conductivity.
Define it, and the error message should go away...
but i dont have cmo in my materials!
this is my code
Code:

The models thermal & lat.temp are commented out.
However I don't know if the lat.temp model contains the CNT thermal conductivity value.
Nor do I know what's meant by CMO. Perhaps an umbrella term for CNT type layer materials?
