The strain induced on pressurized graphene balloons can be estimated directly from the peak shift of the Raman G band. By comparing the measured strain with numerical simulation, we obtained the Young's modulus of graphene. The estimated Young's modulus values of single- and bi-layer graphene are 2.4\\pm0.4 TPa and 2.0\\pm0.5 TPa, respectively.", "revisions": [ { "version": "v1", "updated": "2012-08-11T05:40:17.000Z" } ], "analyses": { "keywords": [ "raman spectroscopy", "estimation", "estimated youngs modulus values", "pressure difference", "bi-layer graphene" ], "tags": [ "journal article" ], "publication": { "journal": "Nano Letters", "year": 2012, "month": "Sep", "volume": 12, "number": 9, "pages": 4444 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012NanoL..12.4444L" } } }
