Such surface oscillations can be considered as a phonon analog of Tamm states well known in the electronic theory. We consider both armchair and zigzag graphene stripes and demonstrate that surface modes correspond to phonons localized at the edges of the graphene nanoribbon, and they can be classified as in-plane and out-of-plane modes. In addition, in armchair nanoribbons anharmonic edge modes can experience longitudinal localization in the form of self-localized nonlinear modes, or surface breather solitons.", "revisions": [ { "version": "v1", "updated": "2010-01-20T05:11:47.000Z" } ], "analyses": { "subjects": [ "61.46.-w", "63.20.Pw" ], "keywords": [ "graphene nanoribbon", "vibrational tamm states", "armchair nanoribbons anharmonic edge modes", "zigzag graphene stripes", "study vibrational states" ], "tags": [ "journal article" ], "publication": { "doi": "10.1103/PhysRevB.81.165418", "journal": "Physical Review B", "year": 2010, "month": "Apr", "volume": 81, "number": 16, "pages": 165418 }, "note": { "typesetting": "TeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010PhRvB..81p5418S" } } }
