Scientists have found a way to turn graphene into a topological insulator – a material that is an insulator in its interior but is highly conducting on its surface. Realizing a topological insulator in graphene could provide a basis for low-dissipation ballistic electrical circuits or could form the material substrate for topologically protected quantum bits.
