This property gives rise to the interesting inverse Edelstein effect (IEE), in which an applied spin bias $\\mu$ is converted to a measurable charge voltage difference $V$. We develop a semiclassical theory for the IEE of the surface states of $\\text{Bi}_2\\text{Se}_3$ thin films, which is applicable from the ballistic regime to diffusive regime. We find that the IEE efficiency ratio $\\gamma=V/\\mu$ exhibits universal dependence on sample size, and approaches $\\pi/4$ in the ballistic limit and $1$ in the diffusive limit.", "revisions": [ { "version": "v1", "updated": "2017-01-12T08:25:41.000Z" } ], "analyses": { "keywords": [ "surface states", "iee efficiency ratio", "three-dimensional topological insulators posses", "measurable charge voltage difference", "interesting inverse edelstein effect" ], "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable" } } }
