Anisotropic electric surface resistance of Cu(110)

Show affiliationsThe electric surface resistance is measured without contacts by grazing incidence of p-polarized infrared (IR) radiation for the adsorbates CO and C2H4, which settle on top of the close packed atomic ridges of Cu(110) in the 
1, -1, 0
direction. Surface resistance has only been observed for the IR electric currents in this direction. This can be explained by the assumption that IR induced currents in the 001 direction can only flow in the second and deeper layers of Cu(110). Therefore, in this direction, there is no friction with the adsorbates and hence no surface resistance.
