Abstract

With the aim of the electronic control of catalytic processes, nano-sized Schottky diodes were fabricated by physical vapour deposition (PVD) as well as spincoating of platinum nanoparticles to n-GaN surfaces. Both methods were suitable to achieve defined coverages, which were in the range of 45% to 95% for PVD particles and 1% to multilayers for spin-coated particles, as investigated by atomic force microscopy. A catalytic conversion of 1% was observed for PVD samples for the hydrogenation of ethene to ethane. The surface properties were investigated by X-ray photoelectron spectroscopy.
