Photoelectron holography of Pt ( 111 ) at 351 eV

Abstract

A 351 eV photoelectron hologram of a Pt(111) surface was collected by detection of photoelectrons from the 4f5/2 subshell in a display analyzer, and was Fourier-analyzed. The real space image showed sensitivity to the fourth atomic layer, excellent reproduction of the fcc lattice, and sixteen source-atom neighbors. Transverse atomic positions were located to 0.1 Å. Photoelectron holography is thus shown to be capable of imaging lattices and interfaces, using low-energy electrons. © 1993.
