Deposition of Pd nanoparticles (NPs) on InP or GaN single crystal wafer was performed from isooctane colloid solution. Diodes were prepared by making Schottky contact with colloidal graphite on Pd NPs partly coated surface and ohmic contact on the blank side of the wafer. It was found that several ppb of hydrogen in nitrogen gas can be detected by monitoring the change of diode current at a constant bias voltage. Diodes made on GaN were about ten times more sensitive to hydrogen than those made on InP.
