  • The formation of structural ripples has been shown to control the local electronic properties in graphene. Okadaet al. use scanning tunnelling microscopy to study the effects of ripples in Bi2Te3topological insulators, and find that buckling modulates the Dirac surface-state dispersion.

  • Spin-orbit Mott materials such as Sr3Ir3O7 and Sr2IrO4exhibit rich correlation-driven physics, which makes them promising candidates for novel electronic states. Here, the authors explore the effect of hole-doping within the spin-orbit Mott phase and show that the carriers localize within a phase-separated ground state.

  • Iridate materials are at present the focus of interest because the combination of strong spin–orbit effects and many-body electronic correlations makes their physics non-trivial. Now, the density of states of Sr3Ir2O7 is mapped out spatially using scanning tunnelling microscopy and spectroscopy, yielding insights into the influence of nanoscale heterogeneities on the electronic structure.
