Imaging Of Cu(001) Atoms By A New Differential Approach To Photoelectron Holography

Abstract

We have applied a new differential method of photoelectron holography to both experimental and theoretical multiple-energy photoelectron diffraction data for Cu 3p bulk emission from Cu(001). Dominant forward-scattering effects contained in a normalized hologram χ(k) have been eliminated by taking the k-difference δχ(k) along each direction. Two data sets that are different in k-space sampling ranges and densities have been analyzed to compare atomic images reconstructed from χ and δχ. In both cases, the original scheme has yielded only very weak images of back-scattering atoms and spurious features in the forward-scattering directions. On the other hand, the differential scheme has been found to be successful in suppressing the forward-scattering effects to image not only side-scattering and back-scattering atoms in either case, but also forward-scattering atoms in one of the two cases.
