The MR grows with field and exhibits a maximum at fields B>1/\\mu, where \\mu is the electron mobility. As temperature increases the magnitude of the maximum grows and its position moves to higher fields. This effect is universal: it is observed in various Si- and GaAs- based two-dimensional electron systems. We compared our data with recent theory based on the Kohn anomaly modification in magnetic field, and found qualitative similarities and discrepancies.", "revisions": [ { "version": "v1", "updated": "2009-02-10T11:48:21.000Z" } ], "analyses": { "subjects": [ "73.63.Hs", "73.40.Qv", "73.40.Kp", "73.23.Ad" ], "keywords": [ "two-dimensional electron systems", "ballistic regime", "non-monotonic magnetoresistance", "report experimental observations", "perpendicular magnetic field" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review B", "year": 2009, "month": "May", "volume": 79, "number": 20, "pages": 205319 }, "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009PhRvB..79t5319K" } } }
