Schottky barriers on III-V compound semiconductors are still not well explored up to now. There were already reported Pd and Pt Schottky diode gas sensors using InP or GaN materials. However, reported sensing performances are surprisingly different. Thus, proper understanding of sensing mechanism is indispensable. We report on InP and GaN Schottky diode hydrogen sensors with low-leakage currents and high sensitivity, made by deposition of colloidal graphite and electrophoresis of Pd, Pt nebo bimetal Pd/Pt nanoparticles.
