Abstract

We report the discovery of a metal-adatom-induced corrugation of Cu(001) studied by surface-sensitive atom beam scattering (ABS). At a Pb or Bi coverage of 0.05 (fraction of Cu layer), and while a (1×1) low-energy electron diffraction pattern is still observed, the atom beam scattering diffraction pattern of Cu(001) has changed considerably from that of clean Cu(001). We show that the surface has become up to 10 times more corrugated than the clean Cu(001). The nature of this metal-adatom-induced corrugation is ascribed to the redistribution of the Cu(001) surface charge density.
