Recent progress in structure determination by LEED (low-energy electron diffraction)

Surface crystallography with low-energy electron diffraction (LEED) is shown to be developing fast towards solving more complex and diverse kinds of surfaces. This progress is exemplified here with solved structures in three very diverse categories: (1) metal surface reconstructions with multi-layer relaxations: (2) coadsorption of different molecules on metal surfaces; and (3) incommensurate overlayers of graphite on Pt(111). 21 refs., 4 figs.
