The longitudinal resistivity in the center of the $\\nu=\\pm 2$ quantum Hall plateaus vanishes within the measurement noise of 20 m$\\Omega$ upto 2 $\\mu$A. Our results show that the quantization of these plateaus is within the experimental uncertainty (15 ppm for 1.5$ \\mu$A current) equal to that in conventional semiconductors. The principal limitation of the present experiments are the relatively high contact resistances in the quantum Hall regime, leading to a significantly increased noise across the voltage contacts and a heating of the sample when a high current is applied.", "revisions": [ { "version": "v1", "updated": "2008-10-22T13:15:09.000Z" } ], "analyses": { "subjects": [ "73.43.-f", "06.20.-f", "73.23.-b" ], "keywords": [ "quantum resistance metrology", "quantum hall plateaus vanishes", "quantum hall regime", "quantum hall resistance", "relatively high contact resistances" ], "tags": [ "journal article" ], "publication": { "journal": "Applied Physics Letters", "year": 2008, "month": "Dec", "volume": 93, "number": 22, "pages": 222109 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008ApPhL..93v2109G" } } }
