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 AlGaNSi-based solar-blind UV photosensors. Summary of the results 1 the AlGaNGaN HEMT sensors have been processed and tested with water and acetate pica-droplets. 2 PtGaN 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 UVvisible contrast 10e3 have been grown on Si substrates.
