Spin Filtering Ability of Patterned Graphene Nanoribbons
Original language description
The passivated zigzag graphene nanoribbons composed of 2 or 4 atoms wide basis (2-ZGNR or 4-ZGNR) produce strong spin-dependent behavior resulting in a large spin polarization effect. It is shown by analyzing the GNR transmissions calculated by Extended Hückel self-consistent field model (EH-SCF). Our results endorse that for the generation of spin-polarized currents, formation of spin-ordered edge-localized states along the zigzag edges is the key mechanism. We analyzed the influence of various point and planar defects as well as the influence of width and structural composition of GNRs and presented transmission, eigenstates, difference electron densities and electrostatic difference potentials of all respective structures. Since GNRs have long spin-correlation lengths and good ballistic transport characteristics they can be considered as a promising active material of spintronic devices without the need of ferromagnetic electrodes or other magnetic entities. The spin filtering structures could be prepared by the nanolithography of GNR or by the bottom-up approach in future.
