Depositions of Pd nanoparticles (NPs) were performed on surfaces of semiconductor wafers of InP and GaN from isooctane colloid solutions with reverse micelles. Diodes were prepared by making Schottky contacts with colloidal graphite on semiconductor surfaces previously deposited with Pd NPs. Large increase of current was observed after exposing voltage biased diodes to flow of hydrogen and nitrogen blend, representing more than two orders-of-magnitude improvement over the best results reported up to now.
