Abstract

Gallium Nitride epitaxial films were grown by migration enhanced epitaxy directly on sapphire (0001) without using any pre-growth substrate nitridation or low temperature buffer layers. In comparison with our material grown directly on sapphire by conventional molecular beam epitaxy, a significant improvement in the surface morphology and layer properties, measured by reflection high energy electron diffraction, X-ray diffraction, scanning electron microscopy, room temperature photoluminescence and the Hall effect, was observed for material grown by migration enhanced epitaxy.
