我们使用扫描隧道显微镜研究了 C-60 分子在由人工创建的二维空腔组成的纳米结构 Au(111) 表面上的吸附。这些一原子层深的空腔被发现在室温下可以有效地作为分子陷阱。发现台阶边缘处的金原子对 C-60 分子的吸附作出反应，并且在与 R30 度取向的 C-60 分子岛连接的台阶上观察到粗面刻面。提出了结构模型来建立与所有三种类型的分子岛相关的阶梯结构。 (C) 2010 年爱思唯尔作者。版权所有。
We have studied, using scanning tunneling microscopy, the adsorption of C-60 molecules on a nanostructured Au(111) surface consisting of artificially created two-dimensional cavities. These cavities, one atomic layer deep, are found to be effective as molecular traps at room temperature. Gold atoms at step edges are found to respond to the adsorption of C-60 molecules and gross faceting is observed for steps connected with R30 degrees oriented C-60 molecular islands. Structural models are proposed to establish the step structures related to all three types of molecular islands. (C) 2010 Elsevier By. All rights reserved.
