“…3 vs. H 2 pressure for an AlGaN/GaN diode held at V=-2V and T=100 o C. ∆I rapidly increased linearly with pressure in the low-pressure region and then showed saturation at pressures higher than 5 Torr. Liu et al [4] and Chen et al [5] reported similar characteristics for Pd/InP and Pd/GaAs Schottky diodes.…”

Exposure of Pt/GaN and Pt/AlGaN/GaN Schottky diodes to H 2 gas at moderately high temperatures around 100 o C resulted in marked increase of forward and reverse currents. Increase was much larger in the Pt/AlGaN/GaN diode than in the Pt/GaN diode. Rapid turn-on responses and somewhat slower turn-off responses were observed with reproducible response magnitudes. A rigorous computer simulation of I-V curves indicated that current changes are due to changes in the Schottky barrier height caused either by H-induced formation of interfacial dipole or by hydrogen passivation of interface states.

“…The sensor working at high temperatures itself becomes a possible trigger of explosion, due to its enough input electrical energy of sensor operation [1]. The main advantages of Pd-contained sensors on the base of field-effect transistors, MOS structures, and structures with Schottky barrier are possibility to operate at room temperature, high selectivity to hydrogen and low-power consumption [2][3][4][5][6].…”

Pd-anodic oxide-InP metal-oxide-semiconductor (MOS) structures are fabricated to develop a hydrogen sensor capable of effectively operating at room temperature. Through palladium amount varying the signal recovery time has been improved (became shorter). Decrease of photovoltage and strong increase of photocurrent were observed for illuminated by LED structures under hydrogen pulse exposure. The gas testing was carried out in 0.1-10% hydrogen in nitrogen, and in 100% hydrogen. As a result, low power-consumption hydrogen sensor with a fast response-recovery time 1/20 s. was developed.
