Enhanced optical sensitivity to adsorption due to depolarization of anisotropic surface states Article uri icon

abstract

  • The reflectance difference spectroscopy which can be extremely sensitive to the presence of minute amounts of surface defects or impurities was shown. In fact, similar results for metallic and inorganic adsorbates other than CO as well as after sputtering the Cu(110) surface at low temperature were obtained. The strongly enhanced sensitivity to surface defects appears to be related to the delocalized nature of the surface electrons, in particular, of surface states with a large intrinsic anisotropy.
