Multiple-wavenumber photoelectron holography of Pt(111)

A multiple-wavenumber photoelectron holographic study of a Pt(111) surface, based on the 4f 5 2 peak, demonstrates the capability of imaging atomic positions up to three layers above the emitter, with twin images removed by phase-summing over the carefully selected wavenumber range k = 8.8-10.2 Å-1. Photoelectron holography based on synchrotron radiation and forward scattering should be directly applicable to surface and near-surface interface systems. © 1994.
