Abstract:Herein, the spin‐polarized edge‐state transport properties in L‐shaped zigzag nanodevice () are investigated based on tight‐binding model, Green's function method, and ballistic transport theory. The spin conductance and spin polarization are calculated by considering external exchange field and electric field. It is shown in the results that the spin conductance is closely related to the configuration of atomic non‐consistence on the edge of . Meanwhile, the spin conductance is determined by the spin channel… Show more
