Graphene nanoribbons grow due to domino-like effect

(PhysOrg.com) — While many labs are trying to efficiently synthesize large two-dimensional sheets of graphene, a team of researchers from Sweden and the UK is investigating the synthesis of very thin strips of graphene just a few atoms wide. In contrast to graphene, these graphene nanoribbons have a unique electronic structure including a non-zero band gap, which makes them promising candidates for semiconductor applications. But, as with graphene sheets, one of the greatest challenges for now is finding a way to efficiently synthesize these graphene nanoribbons.
