Application of an oscillating voltage in the GHz-range to one of two top gates, crossing a narrow wire and confining a quantum dot, leads to quantized pumped current plateaus in the gate characteristics. The regime of pumping one single electron is traced back to the diverse tunneling processes into and out-of the dot. Extending the theory to multiple electrons allows to investigate conveniently the pumping characteristics in an applied magnetic field. In this way, a qualitatively different behavior between pumping even or odd numbers of electrons is extracted.", "revisions": [ { "version": "v1", "updated": "2009-09-15T11:50:50.000Z" } ], "analyses": { "keywords": [ "single electrons", "non-adiabatic pumping", "perpendicular magnetic field", "narrow wire", "diverse tunneling processes" ], "tags": [ "journal article" ], "publication": { "journal": "Physica E Low-Dimensional Systems and Nanostructures", "year": 2010, "month": "Feb", "volume": 42, "number": 4, "pages": 911 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010PhyE...42..911L" } } }
