The white dots making up squares arrayed 45 - degrees to the x / y - axis are selenium (Se) atoms, while the defects — missing Fe atoms in the Fe plane, about a quarter of
a nanometer below the Se surface — show up as butterfly - shaped perturbations produced by quantum interference of electrons scattering from the defects.
