【摘要】 利用Au催化辅助化学气相沉积生长技术,在nSi(111)衬底上制备了准单晶的ZnO纳米线。X射线衍射分析的结果表明,ZnO纳米线具有明显的沿(0001)方向定向生长的特征。扫描电子显微镜分析表明,ZnO纳米线的典型直径约为100nm,长度为2～5μm。讨论了Au催化辅助化学气相沉积生长技术制备ZnO纳米线的原理。更多还原

【Abstract】 ZnO nanowires have been grown on Au coated n-Si (111) substrates by chemical vapor deposition and Au catalytic technology.The structure and morphology of ZnO nanowires had been studied by X-ray diffraction (XRD) and scanning electron microscope (SEM).It is found that ZnO nanowires are highly orientedly grown in the direction of (0001).SEM images of ZnO nanowires have shown that the typical diameter and length of ZnO nanowires are 100nm and 2~5μm,respectively.The growth mechanism of ZnO nanowires has also been discussed.更多还原
