Abstract

Go halves on metals The existence of curious materials called 'half metals' is predicted: they are metallic only for half of the available free electrons, namely those in a particular spin orientation. For the other half of electrons, with the opposite spin, a half-metal is insulating. There is some experimental evidence for half-metallic behaviour, and substantial efforts are being made to find such materials that could be of practical use in spintronics. Based on first-principles calculations, Son et al. predict half-metallic behaviour in nanometre-scale ribbons of graphene. The property emerges when homogeneous electric fields are applied across the nanoribbons, with the zigzag-shaped edges attached to the voltage contacts. This work could be a step towards graphene-based nanospintronics.
