S-decorated Cu trimers are a likely agent of S-enhanced Cu transport between islands on Cu(111). According to ab initio calculations, excellent S bonding to trimer-Cu dangling valence results in an ad-Cu{sub 3}S {sub 3} formation energy of only {approx}0.28 eV , compared to 0.79 eV for a self-adsorbed Cu atom, and a diffusion barrier {<=}0.35 eV .
