Planar Hall effect from the surface of topological insulators

Topological surface states can lose their protection in many ways but the subtle mechanisms remain far from well understood. Here, Taskin et al. report a novel planar Hall effect in dual-gated Bi2−x Sb x Te3 thin films, originating from anisotropic lifting of time reversal symmetry protection by an...
