ABSTRACTThe deposition of Cu onto Au(100) and of Pb onto n- Si(111) electrodes from aqueous solutions has been monitoredin situby scanning tunneling microscopy. In the first case, a bcc structure of the Cu overlayer is observed, which allows pseudomorphic growth on Au(100) up to the 10th layer. Then a slow structural transition to fee begins. In contrast, Pb on Si(111) is shown to deposit as 3D crystallites with flat (111) terminated surfaces.
