Abstract:We report the discovery of a metal adatom induced corrugation of Cu(001) as probed by atom beam scattering (ABS). At Pb or Bi coverages of 0.05 (fraction of Cu layer), and while a (1×1) LEED pattern is still observed, the ABS diffraction pattern from uncovered Cu(001) areas has changed considerably from that of clean Cu(001). We show that these uncovered areas have become up to ten times more corrugated than the clean Cu(001). We performed several carefully designed experiments to test whether our data could b… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
