I am studying the different types of the TFET structure with the Sentaurus TCAD. It is worth mentioning that I have studied several papers in this regard and I want to simulate to the both junctionless TFET. but I am facing a problem regarding to the band-to-band tunneling taking place in the device and at simulating the aforementioned device.I would appreciate if anyone could please inform me how can I able to define the junctionless TFET structure in the sentaurus structure editor (SDE) and simulation to be done using Sdevice ?
