To observe the difference of atomic heights between the Se and Te layers with respect to the Fe layer in FeSe0.4Te0.6 single crystal, a Fe Kα fluorescence X-ray holography (XFH) experiment was performed at room temperature. The crystal structure of superconductor FeSe0.4Te0.6 obtained by X-ray diffraction (XRD) at a low temperature has distinct z-coordinates of Se and Te, remarkably different from each other. The reconstructed atomic image around central Fe atoms by XFH, however, reveals the different and complex results.
