  bibo_abstract:
  - Despite many efforts to rationalize the strongly correlated electronic ground
    states in doped Mott insulators, the nature of the doping-induced insulator-to-metal
    transition is still a subject under intensive investigation. Here, we probe the
    nanoscale electronic structure of the Mott insulator Sr₂IrO₄δ with low-temperature
    scanning tunneling microscopy and find an enhanced local density of states (LDOS)
    inside the Mott gap at the location of individual defects which we interpret as
    defects at apical oxygen sites. A chiral behavior in the topography for those
    defects has been observed. We also visualize the local enhanced conductance arising
    from the overlapping of defect states which induces finite LDOS inside of the
    Mott gap. By combining these findings with the typical spatial extension of isolated
    defects of about 2 nm, our results indicate that the insulator-to-metal transition
    in Sr₂IrO₄−δ could be percolative in nature.@eng
