Nanoscale electron transport at the surface of a topological insulator
Topological insulators offer lossless surface transport because of the suppression of conduction-electron backscattering from defect sites. Here, the authors show that the nanoscale voltage drops caused by such scattering can be directly measured using scanning tunnelling potentiometry.
