Observation of surface states on heavily indium doped SnTe(111), a superconducting topological crystalline insulator

C. M. Polley, V. Jovic, T. -Y. Su +10

The topological crystalline insulator tin telluride is known to host superconductivity when doped with indium (Sn${}_{1-x}$In${}_x$Te), and for low indium contents ($x=0.04$) it is k…
