Title Quantum tunneling through graphene nanorings Type A1 Journal article
Year (down) 2010 Publication Nanotechnology Abbreviated Journal Nanotechnology
Volume 21 Issue 18 Pages 185201
Keywords A1 Journal article; Condensed Matter Theory (CMT)
Abstract 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.

Title Resonant tunneling through S- and U-shaped graphene nanoribbons Type A1 Journal article
Year (down) 2009 Publication Nanotechnology Abbreviated Journal Nanotechnology
Volume 20 Issue 41 Pages 415203,1-415203,7
Keywords A1 Journal article; Condensed Matter Theory (CMT)
Abstract We theoretically investigate resonant tunneling through S- and U-shaped nanostructured graphene nanoribbons. A rich structure of resonant tunneling peaks is found emanating from different quasi-bound states in the middle region. The tunneling current can be turned on and off by varying the Fermi energy. Tunability of resonant tunneling is realized by changing the width of the left and/or right leads and without the use of any external gates.
