“…For a reasonably thorough multiple scattering (dynamical) calculation, the present limit is only a few per cent of the above figure. Hence LEED analysis has proceeded using kinematical (single scattering) analysis, which, despite its shortcomings, was still sufficient (Miller and Haneman 1979, Miller et al 1980 to show the incompatibility with experiment of many proposed models. In the last few years more LEED analysis has been carried out and also high-energy transmission electron diffraction of very thin specimens.…”

This article reviews the current state of knowledge of the structure and surface states of several clean low-index faces of silicon. These are the (100) face, the ( 1 1 1 ) 7 x 7 face, the ( I 11)( 1 x 1) face and the ( I 11) 2 x I cleavage face. A new model for the latter is also proposed. Aided particularly by recent scanning tunnelling microscopy results there appear to be grounds for some confidence that the structures of most of the above reconstructed surfaces are now understood. I n addition to reviewing results from a variety of experimental techniques used on clean surfaces, results for gas covered and metal covered surfaces are also summarised.

“…LEED studies have identified metastable configurations (18), some of which disappear with annealing in vacuum (430). Theoretical fits to LEED data have been compared (380). UPS was used in interpretations of surface, bulk, and resonance states in angle-resolved studies of electronic structure of the superlattice (259,238,237).…”
