The junctions were fabricated on top of a thin silicon nitride membrane, which was actuated with an AFM tip attached to a stiff cantilever. A large relative change in the tunneling resistance in response to the applied strain (gauge factor) was observed, up to a value 37. This facilitates local static strain variation measurements down to ~10^{-7}.", "revisions": [ { "version": "v1", "updated": "2009-06-23T12:05:42.000Z" } ], "analyses": { "subjects": [ "07.07.Df", "07.10.Pz" ], "keywords": [ "sub-micron sized al-alox-al tunnel junctions", "strain sensing", "local static strain variation measurements", "facilitates local static strain variation" ], "tags": [ "journal article" ], "publication": { "doi": "10.1063/1.3298582", "journal": "Review of Scientific Instruments", "year": 2010, "month": "Feb", "volume": 81, "number": 2, "pages": 3901 }, "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010RScI...81b3901K" } } }
