Transport properties of armchair graphene nanoribbon junctions between graphene electrodes.
The transmission properties of armchair graphene nanoribbon junctions between graphene electrodes are investigated by means of first-principles quantum transport calculations. First the dependence of the transmission function on the size of the nanoribbon has been studied. Two regimes are highlighted: for a small applied bias transport takes place via tunneling and the length of the ribbon is t...
متن کاملHalf - metallic Armchair Graphene Nanoribbon
Submitted for the MAR10 Meeting of The American Physical Society Half-metallic Armchair Graphene Nanoribbon FUMIYUKI ISHII, KEISUKE SAWADA, MINEO SAITO, Kanazawa University — Among a variety of applications of graphenes, spintronics applications are considered to be hopeful. For an example, spin transport has been experimentally observed by using graphene layers [1]. There are two types of shap...
متن کاملConductance of Graphene Nanoribbon Junctions and the Tight Binding Model
Planar carbon-based electronic devices, including metal/semiconductor junctions, transistors and interconnects, can now be formed from patterned sheets of graphene. Most simulations of charge transport within graphene-based electronic devices assume an energy band structure based on a nearest-neighbour tight binding analysis. In this paper, the energy band structure and conductance of graphene ...

متن کاملVery large magnetoresistance in graphene nanoribbons
Graphene has unique electronic properties, and graphene nanoribbons are of particular interest because they exhibit a conduction bandgap that arises due to size confinement and edge effects. Theoretical studies have suggested that graphene nanoribbons could have interesting magneto-electronic properties, with a very large predicted magnetoresistance. Here, we report the experimental observation...
