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...

Description
Summary: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 superconducting electrodes.
