英文摘要	we investigate theoretically quantum transport through graphene nanorings in the presence of a perpendicular magnetic field. our theoretical results demonstrate that the graphene nanorings behave like a resonant tunneling device, contrary to the aharonov-bohm oscillations found in conventional semiconductor rings. the resonant tunneling can be tuned by the fermi energy, the size of the central part of the graphene nanorings and the external magnetic field.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-05-04t14:03:16z no. of bitstreams: 1 quantum tunneling through graphene nanorings .pdf: 1764049 bytes, checksum: 615488a92aa9db6d5f2a72ccad81d6d1 (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-05-04t14:12:04z (gmt) no. of bitstreams: 1 quantum tunneling through graphene nanorings .pdf: 1764049 bytes, checksum: 615488a92aa9db6d5f2a72ccad81d6d1 (md5); made available in dspace on 2010-05-04t14:12:04z (gmt). no. of bitstreams: 1 quantum tunneling through graphene nanorings .pdf: 1764049 bytes, checksum: 615488a92aa9db6d5f2a72ccad81d6d1 (md5) previous issue date: 2010; chinese academy of sciences；bilateral project between china and sweden ；flemish science foundation (fwlo-vl)；belgium science policy (iap); 国际
