代替タイトル: (0001)サファイア基板上におけるツインフリーα-Ga2O3のHVPE成長
説明:
(abstract)The halide vapor phase epitaxy of a-Ga2O3 is demonstrated for the first time. The films are twin-free, heteroepitaxially grown on sapphire (0001) substrates using gallium chloride and oxygen as precursors. The growth rate reaches approximately 150 um/h, which is over two orders of magnitude larger than those of conventional vapor phase epitaxial growth techniques. X-ray omega-2theta and pole figure measurements reveal that the film is single-crystalline (0001) a-Ga2O3 with no detectable formation of a-Ga2O3. The optical bandgap is determined from the transmittance spectrum to be 5.16 eV.
