โœฆ Synopsis

Using a perturbative method, the influence of a single magnetic impurity on the spin-polarized current flowing through a metallic armchair graphene nanoribbon is investigated theoretically. It is shown that the nonlinear correction depends strongly on the relative spin orientations in the two spin-polarized reservoirs. Also, the effects of magnetic impurity position and width of nanoribbon on the nonlinear conductance are discussed.

By using a simple method, the effects of a substitutional magnetic impurity on the conductance of metallic single-wall carbon nanotubes, lying between two spin-polarized electron reservoirs, are studied. It is demonstrated how the differential conductance depends sensitively on the radius and length

We have investigated transport characteristics of epitaxial graphene grown on semi-insulating siliconface 4H-silicon carbide (SiC) substrate by thermal decomposition method in relatively high N 2 pressure atmosphere. We have succeeded in forming 1-2 layers of graphene on SiC in controlled manner. Th

Co atoms will permeate into the soft organic material to form a magnetic permeated sublayer (MPS) during the fabrication of an organic spin device, such as Co/OSC/LSMO. We considered the OSC as a two-sublayer structure of MPS and pristine OSC, and then established a dynamic spin-diffusion equation t
