| 摘 要： | 以多孔阳极氧化铝为模板,采用两步交流电脉冲沉积法制备具有单晶结构的有序金纳米线阵列.实验表明:在氧化铝模板中由交流电沉积制备的金属纳米线,其成核电压直接影响模板内纳米线的填充率,而生长电压则控制纳米线的结构和形貌均一性.在最佳沉积条件下得到的金纳米线阵列,其填充率高达95%,且具有单晶结构.

| Abstract: | The monocrystalline metal nanowire arrays were prepared by using a two-step AC electrodeposition in porous anodic aluminum oxide (AAO) template. The growth mechanism of nanowires was discussed. As a result, it has been found that the second voltage pulse has a considerable effect on the pore-filling ratio, the uniformity and the crystal structure, whereas the initial voltage pulse affects only the pore-filling ratio. Using the two-step AC electrodeposition, a highly ordered monocrystalline metal nanowire arrays with a pore-filling ration above 95% can be easily obtained. |
