Numerical investigation on AlGaN/GaN short channel HEMT with AlGaN/InGaN/AlGaN quantum well plate

A short channel AlGaN/GaN HEMT with AlGaN/InGaN/AlGaN quantum well plate is proposed and investigated. Benefited by the 2DEG confining effect and plated-like function, the QWP-HEMT exhibits weaker short channel effects and stronger reverse blocking, where in maximum the DIBL reduction and the critical electric field improvement are 88.9% and 88.2% respectively, which suggests the potential for its high-power application in small scale integration.
