Abstract
Atomically resolved scanning tunneling microscopy on Cu/Pb(111) reveal s a new growth mode, contrary to the Volmer-Weber mode expected from t he significantly lower surface energy of Pb. (111)-oriented Cu islands with a thickness of 3-11 layers are immersed in the Pb substrate and covered by a single close-packed Pb layer. This subsurface growth mode occurring at room temperature can be explained by simple thermodynami c considerations.
