Three-dimensional topological insulators host surface states with linear dispersion, which manifest as a Dirac cone. Nanoscale transport measurements provide direct access to the transport properties of the Dirac cone in real space and allow the detailed investigation of charge carrier scattering. Here we use scanning tunnelling potentiometry to analyse the resistance of different kinds of defects at the surface of a (Bi<sub>0.53</sub>Sb<sub>0.47</sub>)<sub>2</sub>Te<sub>3</sub> topological insu ...[more]
