Abstract:The protected surface conduction of topological insulators is in high demand for the next generation of electronic devices. What is needed to move forward are robust settings where topological surface currents can be controlled by simple means, ideally by the application of external stimuli. Surprisingly, this direction is only little explored and the role of topological states in such processes has remained obscure. In this work we demonstrate that we can boost the surface conduction of a topological insulato… Show more
