On the basis of first-principles computational approaches, we present a newmethod to drive zigzag graphene nanoribons (ZGNRs) into the half-metallic stateusing a ferroelectric material, poly(vinylidene fluoride) (PVDF). Owing tostrong dipole moments of PVDFs, the ground state of the ZGNR becomeshalf-metallic when a critical coverage of PVDFs is achieved on the ZGNR. Sinceferroelectric polymers are physisorbed, the direction of the dipole field inPVDFs can be rotated by relatively small external electric fields, and theswitching between half-metallic and insulating states may be achieved. Ourresults suggest that, without excessively large external gate electric fields,half-metallic states of ZGNRs are realizable through the deposition offerroelectric polymers and their electronic and magnetic properties arecontrollable via noninvasive mutual interactions.
