Missing-row surface reconstruction of Au(113) induced by adsorbed calcium atoms

The structure of the (1 x 2) reconstruction induced by 0.1 monolayer of Ca atoms on the Au(113) surface is reported using medium-energy ion scattering. The data show that the (1 x 2) surface corresponds to a missing-row-type reconstruction. Monte Carlo simulations of the experiment provide a quantit...

Description
Summary:The structure of the (1 x 2) reconstruction induced by 0.1 monolayer of Ca atoms on the Au(113) surface is reported using medium-energy ion scattering. The data show that the (1 x 2) surface corresponds to a missing-row-type reconstruction. Monte Carlo simulations of the experiment provide a quantitative measurement of the atomic positions at the surface. All the displacements in the surface region are such that the resulting structure smooths out the corrugation inherent in a missing-row reconstruction. The relation between this reconstruction and the energy balance between competing surface-electronic-charge densities is discussed.
