Abstract:
We invert high-energy (E greater-than-or-equal-to 400 eV) photoelectron and Auger-electron interference patterns to construct 3D images of surface and interface atoms. A new scheme is introduced to correct the phase shift of the image. Image reconstruction is demonstrated for Si(111) square-root 3 x square-root 3-B, a system in which multiple-scattering effects are small and all source waves are equivalent. Using diffraction results from multiple-scattering slab calculations, we achieve a spatial resolution of 1.0-1.3 angstrom, thus qualifying the technique as a direct structural tool.
