1 The vacancy-enhanced contact friction of graphene is mainly attributed to the vacancy-enhanced out-of-plane deformation flexibility of the graphene and the climbing of the tip out of the vacancy trap (which actually acts as a step edge). Graphite TOR signaling pathway regulator Homo sapiens
2 In present study, by performing a set of classic molecular dynamic (MD) simulations, we demonstrated that the double-vacancy defect in graphene substantially enhanced the contact friction when the tip slides over it, and the pinning effect of the reconstructed lattice of the double-vacancy defect with atoms at the bottom of the tip dominated such influence.
