Abstract

The technique of holographic image reconstruction based on photoelectron detection has been applied to the Pb Si(111)-(√3 × √3)R30°-β phase for a determination of the surface structure. Angle-resolved photoemission from the Pb 5d core level shows intensity oscillations as a function of photon energy. These constant-initial-state spectra were taken at various emission angles and Fourier inverted to yield three-dimensional real-space images of the nearest neighbors to the emitter atom. These images clearly show Pb atoms adsorbed at the T₄ site.
