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.
