摘要

Sulfur-enhanced dynamics of coinage metal(111) surfaces: Step edges versus terraces as locations for metal-sulfur complex formation

The propensity of trace amounts of sulfur adsorbed on coinage metal(111) surfaces to dramatically enhance surface dynamics has been demonstrated by STM observations of accelerated 2D island decay for Cu and Ag. It is generally accepted that this enhancement is due to the formation of adsorbed metal-sulfur complexes which facilitate surface mass transport of the metal. These complexes were originally proposed to form on terraces following extraction of metal atoms from step edges and subsequent combination with sulfur on the terraces. However, even when Th is is the au tho r’s pe er re vie we d, ac ce pte d m an us cri pt.
