摘要
利用低温扫描隧道显微镜对吸附在硫醇膜表面的二维C6 0 岛进行研究 ,首次观察到化学键分辨的C6 0 分子结构 ,并发现一种新型的C6 0 二维取向畴界 .这种畴界仅仅由于两边C6 0 分子的取向不同而存在 ,附近没有结构缺陷 ,畴界附近C6 0 阵列的位置平移序和键取向序都得到了保持 .
A C 60 native cage structure has been observ ed for the first time on a selfassembled monolayer of an alkylthiol with a low temperature scanni ng tunneling microscope. A novel topological order originatin g from the orientation of C 60 molecules has been found with orientational domain boundaries. Both the positional order and bondorientational order are f ully preserved along the domain boundaries. The only difference of the two domai ns is the orientation of the C 60 molecules.
