Web1 Sep 2024 · However, most experimental TFETs are plagued by unwanted trap-assisted tunneling (TAT) and Shockley-Read-Hall (SRH) generation currents, which degrade the swing and increase the leakage floor, hence forming a major roadblock for TFET adoption. It is still unclear which type of traps causes this degradation.
