Abstract

We have measured and calculated the full intensity profiles for Si 2p photoelectron emission from Si(111). and have analyzed these via a two-dimensional Fourier-transform holographic inversion procedure. The resulting images associated with two symmetry-inequivalent emitter types exhibit elongated features corresponding to near-neighbor atoms in the first (111) double layer above a given emitter, and are found to improve in quality if strong forward-scattering peaks are removed in a smooth way.
