Topological insulators, or TIs, have two faces: Electrons flow freely along their surface edges, like cars on a superhighway, but can't flow through the interior of the material at all. It takes a special set of conditions to create this unique quantum state--part electrical conductor, part insulator--which researchers hope to someday exploit for things like spintronics, quantum computing and quantum sensing. For now, they're just trying to understand what makes TIs tick.
