摘要:
Using the method of density function theory (DFT) in combination with none-equilibrium Green's functions, we investigate the behavior of spin-charge transport through a junction of a naphthalene diimide (NDI) between two graphene electrodes with different molecule-graphene linkers. We observe the obvious effects of spin-filtering and the spin-rectifying when the two electrodes are set in different spin configurations. Specifically, the ratio of spin-filtering can be up to almost 100% and the magnitude of magnetoresistance reaches 10(5). More interestingly, we find that the apparent effect of n...
