Revealing intrinsic superconductivity of the Nb/BiSbTe${}_2$Se interface

Andrei Kudriashov, Ian Babich, Razmik A. Hovhannisyan +7

Typically, topological superconductivity is reachable via proximity effect by a direct deposition of superconductor (S) on top of a topological insulator (TI) surface. Here we obse…
