摘要：
This paper presents the analytical performances of an AlGaN/GaN High Electron Mobility Transistor (HEMT) based sensor for the detection of H-2 gas. The model calculates the changes in drain-to-source current and sensitivity of the device due to adsorbed atomic density of gas at the gate terminal. Simulated results indicate that AlGaN/GaN HEMT based floating gate sensors are highly suitable for the extreme environment detection of various gases with concentration as low as similar to ppb level.
