dc.description.abstract | We investigated the performance of NO2 gas sensors based on AlGaN/GaN high electron mobility transistors (HEMTs) at high temperatures up to 500 °C. A 30-nm Pd catalyst layer as the gate of the transistor sensor was deposited by e-beam evaporator for NO2 sensing. At 500 °C, the sensor showed high sensitivity (8.1%), fast response (6 s) and recovery times (7 s) under 1 ppm NO2, thereby proving to be a great candidate for semiconductor sensors under extreme conditions. | - |
