What the difference between Thermionic Trap-Assisted Tunneling (TTAT) and direct tunneling (DT) mechanisms HEMT Transistor ?

18 January 2017 0 5K Report

Hi , i'm looking for leakage current mechanisms and i found the TTAT and the DT , what the difference between the TTAT and DT , are there other mechanisms of leakage current ?

thank you
