A mechanism for this type of breakdown is proposed, based on the generation of magneto-excitons when the quantum Hall fluid flows past an ionised impurity above a critical velocity. The calculated generation rate gives a voltage step height in good agreement with measurements. We also compare this model to a hydrodynamic description of breakdown.", "revisions": [ { "version": "v1", "updated": "2003-06-10T14:53:25.000Z" } ], "analyses": { "keywords": [ "laminar flow", "charged impurity", "quantum hall fluid flows past", "integer quantum hall effect occurs", "experiment" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable" } } }
