Wear properties of graphene edges probed by atomic force microscopy based lateral manipulation

Excellent elastic properties and good adhesion of graphene to substrate make graphene a promising candidate for application in various friction and wear protective coatings. In order to investigate the response of graphene edges on lateral forces, we combine atomic force microscopy (AFM) based experiments with large scale molecular dynamics (MD) simulations. Exploring movement of AFM tip across graphene edges, we identify four consecutive...
