摘要： 采用直流电沉积的方法在氧化铝模板（AAM）中成功地制备了Sb单晶纳米线阵列. X射线衍射（XRD）证明所制得的纳米线阵列为(110)取向的六方相Sb.透射电镜（TEM）显示Sb纳米线平滑而均匀,直径40～50 nm,长径比大于1000.选区电子衍射（SAED）结果表明,所制得的纳米丝为Sb单晶丝.场发射扫描电镜（FE-SEM）显示Sb纳米线阵列规则,填充率接近100％.

Abstract: Highly uniform Sb nanowire arrays have been fabricated using electrochemical deposition into nanochannels of porous anodic alumina membrane (AAM). X-ray diffraction (XRD) patterns show that the deposited material is hexagonal Sb orientating along the (110) direction. The transmission electron microscope (TEM) observations demonstrate that the diameter of the nanowires is about 40～50 nm, which is the same as that of the AAM used, and the aspect ratio of the nanowires is over 1000.The selected area electron diffraction (SAED) patterns show that the Sb nanowires are single crystals. The field emission scanning electron microscope (FE-SEM) results indicate that the Sb nanowire arrays are highly uniform, and the filling-rate is almost 100％. Finally, several aspects about how to prepare high-quality metal nanowire arrays are also discussed.
