基于纳米操作机器人的石墨烯切割力各向异性研究

Cutting force anisotropy dependence on lattice structures of graphene based on nanorobot

石墨烯的独特之处在于其电学特性与其边缘结构几何构型密切相关,而如何大规模可控地剪裁石墨烯是石墨烯走入实际应用的前提.利用纳米操作机器人技术,从实验上系统研究了石墨烯切割力与切割方向的关系,结果表明石墨烯切割力各向异性,与石墨烯的晶格结构相吻合.这表明在石墨烯加工过程中,实时切割力可作为反馈信息从而实现石墨烯的可控加工.

The unique of graphene is that its electrical properties are strongly related to its size, geometry, and edge structures. How to tailor graphene in a controllable way is the premise for real applications. This work systematically investigates the relationship between cutting forces and cutting directions based on the nanorobot. The results show that the cutting forces of graphene are anisotropy which have a good match with latttice structures. This shows that the real-time cutting forces can be used as feedback information to control the cutting directions during the manufacturing process.
