Atomic Coordinates

The Si ((113) 3×1-H structure has been investigated by a quantitative low-energy electron diffraction intensity analysis. A model with two Si dimers in the unit cell gives best agreement between the calculation and the experimental data. Three-dimensional atomic coordinates have been determined.

Band Mapping

Resolving the 3D wave vector k in photoemission mapping of the band structure E( k ) requires knowledge of the unoccupied final states. Both dispersions and lifetimes of these states can be achieved by very-low-energy electron diffraction (VLEED). By incorporating the non-free-electron and excited-state effects in the final states, combining VLEED with photoemission provides accurate mapping of the valence E( k ) resolved in the 3D wave vector and under control of the intrinsic accuracy. We here concentrate on the most accurate combined method which uses angle-dependent VLEED and photoemission measurements. It provides access to many Brillouin-zone lines using one crystal surface, and benefits from an intensity gain and a better intrinsic accuracy near the Fermi level.
