X-ray fluorescence holography (XFH) provides three-dimensional atomic images around specific elements without any assumption of the structural model. Six X-ray holograms Si0.8Ge0.2/Si at different energies were measured at the synchrotron radiation facility of SPring-8. Si and/or Ge atoms within 0.7 nm of a radius were clearly visible in the atomic images reconstructed from the holograms. From these images, slight displacements of the images at each shell in between Si0.8Ge0.2/Si and the Ge bulk were distinctly revealed. This demonstrated that the XFH method has a great potential to quantitatively analyze a three-dimensional local lattice structure in epitaxial crystals.
