Abstract

Using medium-energy ion scattering with channeling and blocking, we have investigated the (1X2) reconstructions of Ni(110) and Au(113) (stabilized by submonolayer amounts of K and Ca, respectively). Our data contain evidence that the two surface structures correspond to missing-row type reconstructions. Monte Carlo simulations show that the first interlayer spacing of the (1X2)-Au(113) surface undergoes a large contraction ( — 18.6%), while the first interlayer spacing of (1X2)-Ni( 110) undergoes a small, unexpected expansion (+3%). Although the symmetry of Au(113) allows a lateral registry shift, none is found. Our structural models are discussed in terms of the energy balance between competing surface electronic charge densities.
