It is shown that contrary to the tunneling through a potential barrier, the transmission of electrons is, in this case, smaller than one for normal incidence. This mechanism may be useful for designing electronic devices made of graphene.", "revisions": [ { "version": "v1", "updated": "2008-05-14T13:45:03.000Z" } ], "analyses": { "keywords": [ "dirac electrons", "spatial regions", "finite mass", "electronic spectrum changes", "usual linear dispersion" ], "tags": [ "journal article" ], "publication": { "journal": "Journal of Physics Condensed Matter", "year": 2008, "month": "Aug", "volume": 20, "number": 32, "pages": 325221 }, "note": { "typesetting": "TeX", "pages": 24, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008JPCM...20F5221V" } } }
