| 摘 要： | 在不用催化剂的条件下,通过热蒸发锌粉的方法,一种新颖的球棒状的氧化锌纳米结构被沉积在硅基片上.每一根球棒状的氧化锌纳米棒("纳米球棒")由三部分构成,分别是六边形"球棒头"、"球棒把手"以及一个连接过渡的部分.高分辨率透射电镜和选区电子衍射结果表明,纳米棒呈单晶特性,沿着0001]方向择优生长.根据对实验结果的分析,纳米球棒的生长过程可以利用气-固生长机制进行解释,合理地提出其生长模型.

| Abstract: | A novel bat-like ZnO nanostructure was synthesized on the silicon substrate by simple ther-mal evaporation of zinc powders without any catalyst. Each bat-like nanorod ("nanobat") is composed of a hexagonal head, a continuous neck and a thin handle. High-resolution transmission electron microscopy and selected area electron di raction results reveal the single-crystalline feature and the growing direction along 0001] of the nanobat. The vapor-solid mechanism was found suitable to explain the growth process of the nanobat and a schematic model was proposed in detail based on the experimental results. |
