                      and co-workers demonstrate nanoscale four-probe measurements
                      on atomically thin topological insulator films. For this
                      purpose, four individual scanning tunneling microscope tips
                      are directly contacting individual terraces on the sample
                      surface to quantify the thickness-dependent film
                      conductivity. This enables the authors to detect a breakdown
                      of spin-momentum locking in the topological surface state as
                      a function of the film thickness. In the few-layer limit,
                      this effect can realize helical edge modes along step edges
                      with potential applications in spintronics and quantum
                      computing.},
