Based on our analytical and numerical results, we show that with increasing the energy gap of TI surface states, the $\\Phi_{0}/2$=$hc/2e$ periodic AB oscillations in spin-resolved LDOS gradually transit into the $\\Phi_{0}$ periodic oscillations.", "revisions": [ { "version": "v2", "updated": "2012-03-28T02:42:58.000Z" } ], "analyses": { "subjects": [ "73.20.Fz", "71.20.Ps", "71.70.Ej", "73.20.At" ], "keywords": [ "analogous weak antilocalization", "topological insulator surface", "aharonov-bohm interferometer", "probing crossover", "periodic ab oscillations" ], "tags": [ "journal article" ], "publication": { "doi": "10.1063/1.3697993", "journal": "Applied Physics Letters", "year": 2012, "month": "Mar", "volume": 100, "number": 13, "pages": 133103 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012ApPhL.100m3103F" } } }
