Pyroelectric A1GaN/GaN HEMTs for ion-, gas- and Polar-Liquid Sensors
Abstract
The 18th month progress report includes the results on processing and investigations of (1) pyroelectric HEMT based sensors for polar-liquid molecules detection; (2) Pt GaN Schottky diode hydrogen sensors; (3) AlGaN/Si-based solar-blind UV photosensors. Summary of the results: (1) the AlGaN/GaN HEMT sensors have been processed and tested with water and acetate pica-droplets. (2) Pt/GaN catalytic hydrogen sensors were processed and tested to operate at 350C and RT. (3) high-performance AlGaN solar-blind UV photosensors with a spectral response of 240 - 300 nm and UV/visible contrast > 10e3 have been grown on Si substrates.
