Abstract

We investigate the effects of defects on the optical response of the Cu(110) surface in the spectral region dominated by transitions between surface states. By modeling the variation of reflection anisotropy spectroscopy (RAS) signal with defect coverage we investigate the length scale over which a defect quenches the 2.1 eV RAS peak. We consider a number of different defect types; adatoms, vacancies, and molecular adsorbates, and find that all quench the RAS signal in this region by similar amounts.
