Surface Structures and Transitions and the Evolution from Firm to Bulk Behavior
Abstract
This research program has concentrated on two main areas of research: (a) the structures and transitions of monolayers and multilayers of rare gases including krypton and xenon on single crystal graphite (b) the thermal roughening of simple metal surfaces. The simple systems of rare gases on a triangular surface have shown a remarkable variety of solid phases. This is due to the substrate potential which may have a slightly different periodicity from the bulk phase of the adsorbed species. Advances in cell powder design, together with high brightness synchrotron radiation x-ray sources, have made possible studies on one single crystal substrate; this allows one to investigate the structures and orientations of these solid layers in fine detail. Xenon monolayers on a single crystal graphite surface and investigated using beam-line X-20A. A 1 mm x 1 mm focused beam is used with an Di double monochromator and a Ge analyzer.
