A composite structure consisting of graphene layers and fullerene molecules is fabricated and their mechanical properties are investigated by scanning probe microscopy (SPM). A large size of graphene (~0.5 mm) has been synthesized by controlling the substrate morphology as well as the density of nuclei using a custom-made chemical vapor deposition apparatus. Monolayer fullerene films are successfully grown and the surface is characterized by friction force microscopy. It was found that the fullerene layers show lower friction than the graphite surface. The clean transfer method enables us to fabricate graphene/fullerene/graphene model structure for the development of nano-manipulation in the nano-space sandwiched between graphenes.

制备了由石墨烯层和富勒烯分子组成的复合结构，并通过扫描探针显微镜（SPM）研究了它们的机械性能。通过使用定制的化学气相沉积设备控制基底形态和核密度，合成了大尺寸石墨烯（~0.5 mm）。单层富勒烯薄膜成功生长，并通过摩擦力显微镜对其表面进行了表征。研究发现，富勒烯层的摩擦力低于石墨表面。清洁转移方法使我们能够制造石墨烯/富勒烯/石墨烯模型结构，以开发夹在石墨烯之间的纳米空间中的纳米操纵。
