Witrynakink in GaN HEMTs has been attributed to impact ionization [5]. However, the fact that the kink is often seen just a few volts (as little as 2 and 3 V) above the knee makes it implausible for the carriers to have sufficient energy to cause impact ionization and provide a supply of holes. As a result, models have been suggested based on the ... Witryna13 cze 2024 · In this paper, we hypothesize that this enhancement is due to the interfacial ionization phenomenon.
