These particles form localized states called edge states on finite width strip with zigzag edges at E = 0. Naively thinking, one may expect that current is also concentrated at the edge, but Zarbo and Nikolic numerically obtained a result that the current density shows maximum at the center of the strip. We derive a rigorous relation for the current density, and clarify the reason why the current density of edge state has a maximum at the center.", "revisions": [ { "version": "v2", "updated": "2009-05-07T08:25:20.000Z" } ], "analyses": { "keywords": [ "zigzag edges", "graphene strip", "uniform current", "current density", "edge state" ], "tags": [ "journal article" ], "publication": { "doi": "10.1143/JPSJ.78.065003", "journal": "Journal of the Physical Society of Japan", "year": 2009, "month": "Jun", "volume": 78, "number": 6, "pages": 65003 }, "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009JPSJ...78f5003N" } } }
