However, alloy scattering has till now been treated in an empirical fashion with a fitting parameter. We present a theoretical model within the atomistic tight-binding representation for treating alloy scattering in SiGe. This approach puts the scattering model on a solid atomistic footing with physical insights. The approach is shown to inherently capture the bulk alloy scattering potential parameters for both n-type and p-type carriers and matches experimental mobility data.", "revisions": [ { "version": "v3", "updated": "2011-03-01T19:52:50.000Z" } ], "analyses": { "subjects": [ "72.20.Dp", "72.20.Fr" ], "keywords": [ "atomistic approach", "bulk alloy scattering potential parameters", "matches experimental mobility data", "atomistic tight-binding representation", "sige alloy" ], "tags": [ "journal article" ], "publication": { "journal": "Applied Physics Letters", "year": 2011, "month": "Apr", "volume": 98, "number": 17, "pages": 173503 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011ApPhL..98q3503M" } } }
