Does Sentaurus TCAD have the material model for aIGZO and poly-Si inbuilt (or found in some other resource)? Is it possible to simulate aIGZO and poly-Si based TFT using channel material properties such as acceptor-like trap state, donor-like trap state, gaussian trap states, etc. similar to in Silvaco TCAD?
Any articles simulating aIGZO or LTPS TFT in Sentaurus would be of great help too. Thank you in advance.
Dear Premkumar Vincent ,
welcome!
I will give you a conceptual answer. It is so that you have to at first characterize your semicondcutor material in a manner like those materials described in the material library in SILVACO.
So, you have to know:
- Its Eg,
- Its electron affinity X,
- Its conduction type and doping, such as i, p, or n-type
- Its mobility
- Its trap density at the surface and in the bulk
- Its dielectric constant.
The metals which make ohmic contact with the your material.
The you can include your materials in the library of the simulator
or describe them in the input file!
I think your materials will be intrinsic.
Best wishes
