Evidence for higher order topology in Bi and Bi0.92Sb0.08

Evidence for higher order topology in Bi and Bi0.92Sb0.08

The experimental realization of higher order topological insulator (HOTI) in solid state materials remains elusive. Here, Aggarwal et al. reveal hinge states on three edges of both Bi and Bi0.92Sb0.08 (110) islands, supporting them as a class of HOTI.
