I am working towards line tunneling based TFETs, where gate is placed on the source. Now, if , source overlap is increased than the current should increase. But unfortunately, my simulation fails to obtain the same using ebarriertunneling model of Sentaurus TCAD, where a non local mesh is defined by user.

Although the dynamic non local  path model of sentaurus tcad is working well, but AC simulation are not supported. (Here user doesnot define the nonlocal mesh)
