Title: Laser-resonance metal organic chemical vapor deposition of gallium nitride

Abstract: Due to its unique properties, gallium nitride is of great interest in industry applications and scientific research. The processes of conventional methods for gallium nitride deposition, which rely on thermal heating, are inefficient energy coupling routes to drive gas reactions. A high deposition temperature (800-1100 °C) is generally required to overcome the energy barriers to precursor adsorption and surface adatom migration. As an intensive, coherent and monochromatic light, laser is an ideal candidate for exploring alternative energy coupling pathways. The laser techniques offer processing advantages that are not available with conventional deposition methods.
