The goal of a heterojunction TFET (HTFET) is to combine a small effective band gap at the source-channel junction, thus resulting in high I ON, with a large effective band gap at the channel-drain junction to keep I OFF low. In a broken gap alignment, the effective band gap is negative, meaning that there is no forbidden region to tunnel ...
