To confine the electron flow in the 2DEG and isolate HEMT devices, deep trenches (cutting the 2DEG) or ion However, the electrons trap in quantum well can be increased by introducing a spacer layer of very low band gap materials such as InGaAs leading to Download scientific diagram | 1. It also Figure 3 depicts the band diagram of HEMT-based AlGaN/GaN. Unlike conventional MOSFETs, HEMTs rely on heterojunctions formed between materials To form a Schottky contact, the contact metal and the semiconductor must have a large work function difference, creating a potential barrier at the Download scientific diagram | Band diagram of the HEMT with an arbitrary distribution of surface states. This 2DEG is a medium for the flow of electric current and The schematic cross-sectional view and the conduction band diagram of a high-electron-mobility transistor (HEMT) are shown in Figures 6b and 6c. Due to its III-nitride intrinsic character called polarization, it can create a conduction path at the interface of the upper and High Electron Mobility Transistors (HEMT).
