Unusually, this metal is immune to conversion into an insulator by the presence of impurities or distortions on the edge, because its existence is enforced by topological differences between the materials on each side of the edge. Since the theoretical prediction6 and experimental discovery7 of topological-insulator materials in 2006 and 2007, respectively, condensed-matter physicists have been scrambling to exploit the unique properties of the materials in applications such as spintronics and fault-tolerant quantum computing.
