Negative Refraction in Graphene

When graphene meets negative refraction. ‘Graphene and negative refractive-index materials are two of the hottest topics in physics – but one might not think they have much in common. Now, however, physicists in the UK and US have proposed that graphene could be used to make a tiny lens to focus electrons through negative refraction. Although the lens has not yet been made, it could someday be used to focus electrons with much more precision than existing electron lenses (Science 315 5816 ).
