“Topological insulators are recently discovered materials that differ from the familiar insulators and semiconductors in many ways. While topological insulators are fascinating for fundamental physics, they could one day enable electricity with less energy loss, spintronics, and perhaps even quantum computing. Combining theory with experiment, EPFL scientists have now identified bismuth iodide as a topological insulator and the first representative of a whole new structural class of materials that could propel topological insulators into applications. The work, which was carried out within the framework of the EPFL-led NCCR Marvel project, is published in Nature Materials.”
