| description | ► Quantum transport properties of graphene nanoribbons are calculated. ► Graphene nanoribbons exhibit sign-changeable spin-filter efficiency. ► They also show high room-temperature magnetoresistance.
Sign-changeable spin-filter efficiency is predicted in both the ferromagnetic and antiferromagnetic configurations of a zigzag graphene nanoribbon bridging two half-planar graphene electrodes from ab initio quantum transport calculations. By changing edge spin-polarization configuration, we obtain giant room-temperature magnetoresistance, which is one order of magnitude larger than the maximum experimental results. |
