Electron-electron and spin-orbit interactions in armchair graphene ribbons.
The effects of intrinsic spin-orbit and Coulomb interactions on low-energy properties of finite width graphene armchair ribbons are studied by means of a Dirac Hamiltonian. It is shown that metallic states subsist in the presence of intrinsic spin-orbit interactions as spin-filtered edge states, in contrast with the insulating behavior predicted for graphene planes. A charge-gap opens due to Co...
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 کاملElectron transport through honeycomb lattice ribbons with armchair edges
We address electron transport in honeycomb lattice ribbons with armchair edges attached to two semiinfinite one-dimensional metallic electrodes within the tight-binding framework. Here we present numerically the conductance-energy and current-voltage characteristics as functions of the length and width of the ribbons. Our theoretical results predict that for a ribbon with much smaller length an...
متن کاملFlat-band ferromagnetism in armchair graphene nanoribbons
We study the electronic correlation effects in armchair graphene nanoribbons that have been recently proposed to be the building blocks of spin qubits. The armchair edges give rise to peculiar quantum interferences and lead to quenched kinetic energy of the itinerant carriers at appropriate doping level. This is a beautiful one-dimensional analogy of the Landaulevel formation in two dimensions ...
متن کاملPolycrystalline graphene ribbons as chemiresistors.
A IO N Graphene is a two-dimensional semimetal with zero band gap that exhibits excellent electrical, mechanical and thermal properties.[1,2] Transport through delocalized pi bonds allows charge carriers in graphene to achieve high mobility[3,4] for both electrons and holes, over ∼105 cm2/V·s for freely suspended graphene and >104 cm2/V·s for graphene on SiO2. Recent studies have suggested that...
