We demonstrate that increasing the Fermi velocity mismatch in the Sm and S regions can lead to enhanced junction transparency in the presence of spin polarization. We find that the Andreev reflection amplitude at the superconducting gap energy is a robust measure of the spin polarization magnitude, being independent of the strengths of potential and spin-flip scattering and the Fermi velocity of the superconductor.", "revisions": [ { "version": "v1", "updated": "1999-09-01T00:05:22.000Z" } ], "analyses": { "keywords": [ "semiconductor/superconductor hybrid structures", "spin-polarized transport", "hybrid structures depends", "fermi velocity mismatch", "andreev reflection amplitude" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable" } } }
