    Drain current of a TFET is proportioned to tunneling probability Tt. As it can be seen from the picture, Λ is screening length. my question is that can we call Λ, "tunneling...

    This set of slides describes the quantum-mechanical process for tunneling and how it is accounted for in modeling semiconductor devices. We explain WKB approximation, transfer matrix approach and the Tsu-Esaki formula for the calculation of the current.
