Abstract
We have investigated the surface structure of the Al/W(110) surface using low energy electron diffraction (LEED) and low energy ion scattering spectroscopy (ISS). We observe a p(2 Ã 1) double domain LEED image for the 0.5 ML Al/W(110) surface at annealing temperature 850 °C. We found that 0.5 ML Al atoms cover on the W(110) surface uniformly but do not form 3 or 2-dimensional islands. We also measured the Al adsorption site at the Al/W(110)-p(2 Ã 1) surface using ISS. We found that Al atoms adsorbed at the center of the bridge site. The height of the adsorbed Al atoms is determined to be 2.18 ± 0.15 à above the W surface layer.
