Surface Structure Analysis Using Low Energy Ion Scattering. I. Clean Fe(oo1).

Abstract

A clean Fe(001) unreconstructed surface has been analyzed using low energy ion scattering with time of flight energy analysis. The intensity of scattered 9.5 KeV Ne+ ions and neutrals was measured as a function of elevation and azimuth of the incoming beam while keeping a fixed scattering angle of 90 degrees. The observed intensity variations can be described by considering the shadowing and blocking of the second and third atomic layers. A simple Firsov potential was used to calculate the shadow cone dimensions. The good agreement between the observed and calculated variations in scattered intensity demonstrates the utility of this relatively simple technique for preliminary analysis of surface structure.
