Structural analysis of the Cu(100)-p(32×2)R45°-Sn surface using low and medium energy ion scattering spectroscopies

► Deposition of Sn on Cu(100) forms complex reconstructions at submonolayer coverage. ► p(32×2)R45° reconstruction studied with ion scattering and electron diffraction techniques. ► Structure found to be a surface alloy, closely matching the Pussi model.
