Physicists take a step closer to building a graphene-based topological insulator

In 2005, condensed matter physicists Charles Kane and Eugene Mele considered the fate of graphene at low temperatures. Their work led to the discovery of a new state of matter dubbed a “topological insulator,” which would usher in a new era of materials science.
