报道了用气相输运方法合成矩形截面单晶VO2纳米线的方法。这些纳米线的典型直径为60(±30)nm，长度可达~gT；10μm。电子显微镜和衍射测量表明，所制备的VO2纳米线为单晶，具有单斜晶系结构。此外，它们优先沿[100]方向生长，并以(011̄)和(011)面为界。这些VO2纳米线有望为纳米级金属−绝缘体转变的基础研究提供良好的材料。
We report the synthesis of single-crystalline VO2nanowires with rectangular cross sections using a vapor transport method. These nanowires have typical diameters of 60 (±30) nm and lengths up to >10 μm. Electron microscopy and diffraction measurements show that the VO2nanowires are single crystalline and exhibit a monoclinic structure. Moreover, they preferentially grow along the [100] direction and are bounded by the (011̄) and (011) facets. These VO2nanowires should provide promising materials for fundamental investigations of nanoscale metal−insulator transitions.
