Transport evidence of surface states in magnetic topological insulator MnBi2Te4
Michael Wissmann, Romain Giraud, Börge Mehlhorn +8
Magnetic topological insulators can host chiral 1D edge channels at zero magnetic field, when a magnetic gap opens at the Dirac point in the band structure of 2D topological surfac…
