An annealing current through the device changed the transmission coefficient of the electrode/graphene interface, increasing the probability of multiple Andreev reflections. Repeated annealing steps improved the contact sufficiently for a Josephson current to be induced in graphene.", "revisions": [ { "version": "v1", "updated": "2009-03-17T13:50:27.000Z" } ], "analyses": { "subjects": [ "74.45.+c" ], "keywords": [ "proximity effect", "superconductor-graphene-superconductor junction", "multiple andreev reflections", "single graphene layer", "electrode/graphene interface" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review B", "doi": "10.1103/PhysRevB.79.165436", "year": 2009, "month": "Apr", "volume": 79, "number": 16, "pages": 165436 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009PhRvB..79p5436O" } } }
