Ballistic edge states in Bismuth nanowires revealed by SQUID interferometry

Ballistic edge states in Bismuth nanowires revealed by SQUID interferometry

Demonstration of ballistic conduction and spin polarization of edge state currents in two dimensional topological insulators remains a challenge. Here, Muraniet al. report a direct signature of ballistic one dimensional transport along the topological surfaces of a bismuth nanowire connected to supe...
