โœฆ Synopsis


We show by analysis of experimental results that, in the structural study of adsorbed surfaces, the angle-resolved photoemission extended tine structure (ARPEFS) technique has a strong depth sensitivity that can yield unique information about adsorbateinduced substrate near-surface relaxation. Furthermore, we show by theoretical calculations that, in contrast to the generally accepted picture, the enhanced depth sensitivity of ARPEFS arises largely from multiple-scattering effects.
