Energy-spectroscopy of the QD has been performed using a charge sensing technique. The spin relaxation times are subsequently measured in the time-domain by a pump-and-probe method. For the QD that contains an unpaired spin, likely only a single electron, we find that T1 depends strongly on the applied magnetic field. Possible mechanisms leading to the observed spin relaxation are discussed.", "revisions": [ { "version": "v1", "updated": "2009-09-15T19:32:49.000Z" } ], "analyses": { "subjects": [ "73.63.Kv", "72.25.Rb" ], "keywords": [ "silicon mos-based quantum dot", "single electron", "measurement", "spin relaxation time t1", "individual electron spins" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review Letters", "year": 2010, "month": "Mar", "volume": 104, "number": 9, "pages": "096801" }, "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010PhRvL.104i6801X" } } }
