Abstract

We report the use of photoelectron holography for the study of the atomic geometry of the (111) surface of single crystal CoSi₂. We employ as a reference wave the Co 3p core electron emitted with a kinetic energy of 695 eV by absorption of Synchrotron radiation. Remarkably sharp images of the nearest Si neighbors of the Co emitter were found using a computer reconstruction algorithm which compensates for the anisotropies of both reference and object waves. Comparison with other reconstruction schemes such as the Helmholtz-Kirchoff (HK) algorithm and the scattered-wave included Fourier transform (SWIFT), demonstrates the necessity of compensating for the reference-wave anisotropy.
