摘要
报道了用溅射后退火反应法在 Ga As (110 )衬底上制备 Ga N薄膜 .XRD、XPS、TEM测量结果表明该方法制备的 Ga N是沿 c轴方向生长的六角纤锌矿结构的多晶薄膜 .PL测量结果发现了位于 36 8nm处的室温光致发光峰 .
High quality GaN films are prepared by sputtering post annealing reaction technique on GaAs (110) substrates.Measurement results by XRD,XPS,and TEM indicate that the polycrystalline crystal GaN with hexagonal structure is successfully grown.An intense room temperature photoluminescence peak at 368nm of the films is observed.
