Ever since a new class of materials called topological insulators was first created-a discovery that helped win the Nobel Prize in Physics in 2016-researchers have been intrigued by the possibilities for electronics applications such as ultralow-energy transistors, cancer-scanning lasers, and free-space communication beyond 5G. Topological insulators' unusual name stems from their being insulating on the inside and conductive on the outside: On the outer boundaries of a topological insulator, electricity or (in some cases) light flows readily around corners and defects, and with virtually no losses.
