At small currents these states reflect insulating behavior of the electrons in the uppermost Landau level. At larger currents, however, a discontinuous and hysteretic transition to a conducting state is observed. These phenomena, found only in very narrow magnetic field ranges, are suggestive of the depinning of a charge density wave state, but other explanations can also be constructed.", "revisions": [ { "version": "v1", "updated": "1999-07-23T22:34:44.000Z" } ], "analyses": { "keywords": [ "high landau levels", "two-dimensional electrons", "sharp thresholds", "insulating phases", "high-mobility 2d electron systems" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable" } } }
