Schottky barriers were prepared by deposition of colloidal graphite on polished surfaces of InP or GaN single crystals. sparsely covered with Pt nanoparticles deposited electrophoretically. Diodes with the Schottky barriers were studied by current voltage characteristics. The diodes showed high rectification ratio and high Schottky barrier heights indicating negligible Fermi level pinning. By testing with gas consisting of 0.1 % of hydrogen and rest nitrogen, the current showed high sensitivity to hydrogen.
