We theoretically investigate the magnetoresistance (MR) effect in a monolayer graphene modulated by both magnetic and electrical barriers, which can be experimentally realized by depositing two parallel metallic ferromagnetic tripes under an applied voltage on the top and bottom of a graphene. The tremendous MR can be found due to the significant difference between the transmissions through the parallel...
The electron transport properties are theoretically investigated in a nanostructure under the influence of magnetic barriers and the δ-doping. The resulting transmission and spin polarization are strongly dependent on the weight of δ-doping. It is shown that the large spin polarization can be achieved due to the remarkable discrepancy in the transmission for electrons with opposite spin orientations...
A novel method is applied to prepare nanorods. In this method, nanorods have been successfully synthesized on Si(111) substrates through annealing sputtered Ga 2 O 3 /Nb films under flowing ammonia at 950°C in a quartz tube. The as-synthesized nanorods are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy...
