Graphene scroll
WebOct 2, 2015 · Fig. 2 shows the snapshots of graphene (a) scrolling around core tube at 300 K during 100 ps relaxation and (b) unwinding process of CNS driven with 200 GHz rotational frequency of core tube after 919 ps. At the beginning of simulation, the edge atoms of graphene are attracted by core tube due to van der Waals force (Fig. 2(a), 1 st ps). WebApr 17, 2024 · Abstract. The competition between the out-of-plane rigidity and the van der Waals interaction leads to the scrolled and folded structural configurations of graphene. …
