Using atomic force microscopy, we show that the graphene undergoes a sharp \"snap-through\" transition as a function of layer thickness, where the material transitions between conforming to the substrate and lying flat on top of the substrate. By utilizing the critical snap-through thickness in an elasticity model for the FLG's bending, we extract a value for graphene-surface adhesion energy that is larger than expected for van der Waals forces.", "revisions": [ { "version": "v1", "updated": "2011-09-27T16:37:59.000Z" } ], "analyses": { "subjects": [ "68.65.Pq", "68.35.Md", "68.35.Np", "68.55.-a", "68.60.Wm", "62.20.F-" ], "keywords": [ "snap-through instability", "observation", "van der waals forces", "graphene-surface adhesion energy", "atomic force microscopy" ], "tags": [ "journal article" ], "publication": { "doi": "10.1063/1.3676059", "journal": "Applied Physics Letters", "year": 2012, "month": "Jan", "volume": 100, "number": 2, "pages": "021910" }, "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012ApPhL.100b1910S" } } }
