| Popis: | The physical and chemical interaction of an alloy with its environment is dictated not by its bulk composition but by the surface concentration of different elements and their physical arrangement. Of the tools developed to measure these properties, ion scattering (with energies of 0.1–100 keV) has the capacity to measure composition with atomic layer sensitivity and short range order in real space. These advantages have been used to investigate the surface structure, composition and oxidation of bulk alloys and surface alloys. The composition and structure have also been used as probes of order-disorder transitions. In this presentation a review will be undertaken of the information so far delivered by ion scattering, and some of the potential directions will be outlined. Examples of work recently published or currently under investigation will be used to demonstrate the special applications of LEIS to alloy surface studies. |
