We report scanning tunneling microscopy studies of the local structural andelectronic properties of the iron selenide superconductor K0.73Fe1.67Se2 withTC = 32K. On the atomically resolved FeSe surface, we observe well-definedsuperconducting gap and the microscopic coexistence of a charge densitymodulation with root2*root2 periodicity with respect to the original Selattice. We propose that a possible origin of the pattern is the electronicsuperstructure caused by the block antiferromagnetic ordering of the ironmoments. The widely expected iron vacancy ordering is not observed, indicatingthat it is not a necessary ingredient for superconductivity in the intercalatediron selenides.
