本文报道了9,9'-二亚呫吨分子在Ru(0001)上的吸附行为，随后通过扫描隧道显微镜(STM)在室温下研究了石墨烯的自下而上制备过程。在亚单层体系中，9,9'-二亚呫吨分子随机吸附在Ru(0001)上，我们简单分析了它的空间结构。并以 9,9'-二亚呫吨分子为前体，在Ru(0001)衬底上自下而上制备石墨烯，在超高真空中对Ru(0001)衬底进行长时间退火后，发现了具有不同旋转角(6.3°、13.9°和16.1°)的三种摩尔超结构，这是迄今为止未被观察到的，并通过构建模型分析理解了这三种摩尔超结构的形成机制。这个实验为丰富Ru(0001)上摩尔超结构多样性做出了贡献，同时也对以石墨烯/Ru(0001)为基的进一步科学研究打下坚实基础。This paper reports the adsorptions behavior of the 9,9'-Dixanthylidene on Ru(0001), the bottom-up fabrication of graphene was also investigated through a Scanning Tunneling Microscope (STM). We analyzed the spatial structure of 9,9'-Dixanthylidene molecules which were randomly dispersed on the Ru(0001) substrate in the sub-monolayer coverage. Then we bottom-up fabricated the graphene on Ru(0001) substrate with the 9,9'-Dixanthylidene molecules as the precursor. Three kinds of moiré superstructures with different rotation angles (6.3°, 13.9°, and 16.1°) were found after high temperature annealing in an ultrahigh vacuum. This experiment provides data support for the study of moiré superstructures on Ru(0001) substrate and lays a solid foundation for further scientific research based on graphene/Ru(0001).
