Here we use scanning tunneling microscopy (STM) and other experimental tools to characterize SrTiO3, search for orbital nematicity in monolayer FeSe/SrTiO3, and investigate atomic-scale defects that locally influence superconductivity. From quasiparticle interference (QPI) images, we disentangle scattering intensities from the orthogonal Fe 3dxz and 3dyz bands and place an upper bound of δr ~ 20 nm on nematic domain size. Furthermore, we identify “dumbbell”-shaped atomic-scale defects as Fe vacancies.
