High-density large-area nanowire arrays of thermoelectric material Sb(2)Te(3) have been successfully prepared using electrochemical deposition into the channels of the porous anodic alumina membrane. The morphologies, structure, and composition of the as-prepared Sb(2)Te(3) nanowires have been characterized using field-emission scanning electron microscopy, transmission electron microscopy, high-resolution transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. Individual Sb(2)Te(3) nanowires are single crystalline and continuous with uniform diameters ( approximately 50 nm) throughout the entire length. The atomic ratio of Sb to Te is very close to the 2:3 stoichiometry.
通过电化学沉积法将热电材料Sb(2)Te(3)成功制备成了高密度大面积纳米线阵列，沉积于多孔阳极氧化铝膜的通道内。利用场发射扫描电子显微镜、透射电子显微镜、高分辨率透射电子显微镜、X射线衍射和X射线光电子能谱对所制备的Sb(2)Te(3)纳米线的形貌、结构和成分进行了表征。单个Sb(2)Te(3)纳米线为单晶结构，且在整个长度上直径均匀（约50纳米）。Sb与Te的原子比非常接近2:3的化学计量比。
