Zusammenfassung: 
A new growth mode, namely subsurface island growth, has been identified by means of scanning tunneling microscopy. When Cu is deposited on Pb(111), 3D-Cu islands with a thickness between 1 and 11 layers are immersed several layers deep into the Pb substrate. The Cu islands, which can be classified in four different types, are furthermore covered by a monatomic Pb film. On flat Cu islands, this Pb film shows a corrugation that is strongly dependent on the number of Cu layers beneath. Single Cu layers were found to form a new type of Cu-Pb superstructure islands.
