“Signature of ballistic band-tail tunneling current in tunnel FET”. Bizindavyi J, Verhulst AS, Sorée B, Groeseneken G, Ieee Transactions On Electron Devices 67, 3486 (2020). http://doi.org/10.1109/TED.2020.3004119
Abstract: To improve the interpretation of the tunnel field-effect transistor (TFET) measurements, we theoretically identify the signatures of the ballistic band-tail (BT) tunneling (BTT) current in the transfer and output characteristics of the TFETs. In particular, we demonstrate that the temperature dependence of a BTT-dominated subthreshold swing (SS) is in agreement with the reported experimental results. We explain how the temperature dependence of the output characteristics can be used to distinguish between a current dominated by BTT and a current dominated by trap-assisted tunneling. Finally, we propose an expression that relates the energetic extension of the quasi-extended BT states in the bandgap to the onset voltage for tunneling.
