AB  - We report improved sensitivity to NO, NO(2) and NH(3) gas with specially-designed 
      AlGaN/GaN high electron mobility transistors (HEMT) that are suitable for 
      operation in the harsh environment of diesel exhaust systems. The gate of the 
      HEMT device is functionalized using a Pt catalyst for gas detection. We found 
      that the performance of the sensors is enhanced at a temperature of 600  degrees C, and 
      the measured sensitivity to 900 ppm-NO, 900 ppm-NO(2) and 15 ppm-NH(3) is 24%, 38.5% 
      and 33%, respectively, at 600  degrees C. We also report dynamic response times as fast 
      as 1 s for these three gases. Together, these results indicate that HEMT sensors 
      could be used in a harsh environment with the ability to control an 
      anti-pollution system in real time.
