| 1 | Fabrication of hexagonal gallium nitride films on silicon (111) substrates显示文摘Hexagonal gallium nitride films were successfully fabricated through ammoniating Ga2O3 films deposited on silicon (111 ) substrates by electrophoresis. The structure, composition, and surface morphology of the formed films were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM),and transmission electron microscopy (TEM). The measurement results reveal that the polycrystalline GaN films with hexagonal wurtzite structure were successfully grown on the silicon (111) substrates. Preliminary results suggest that varying the ammoniating temperature has obvious effect on the quality of the GaN films formed with this method. | YANGLi XUEChengshan WANGCuimei LIHuaixiang RENYuwen | 2003 | Rare Metals2003，22，3： | 7 |
