Abstract

We draw together the results of two different types of experiments on the Au(110) surface and show they are mutually consistent. Glancing incidence x-ray diffraction showed surface Bragg peaks displaced along [100], indicating that the surface has an average spacing different from the bulk in that direction. The local structure was found to be a 2×1 "missing-row" morphology. Rutherford-backscattering (He+) measurements of the Au(110)-110 surface peak were significantly larger than expected for a simple missing-row model. Lateral displacements in the second layer of the solid are necessary for agreement with both sets of measurements, and the two derived magnitudes (0.12) are the same. Evidence for a large vertical displacement of the top layer is also obtained by both techniques. The inclusion of a specific domain structure along [100] brings this model into agreement with all experimental evidence.
