Abstract
We have investigated the photoelectron diffraction (PED) from a SrF 2 epitaxial thin film on Ge(111) from the viewpoint of holographic inversion for imaging the atomic structure. The holographic interference fringes were retrieved from the PED pattern including a wide variety of diffraction features via averaging the pattern around each forward-scattering peak. Furthermore, another method for enhancing holographic fringes by subtracting one photoelectron hologram from another at slightly different kinetic energies was theoretically investigated.
