Abstract

Stable monoatomic terraces on the (111) Cu surface were imaged by atomic force microscopy during electrodeposition. The terraces originate at screw dislocations and conform to a faceted geometry which reflects the symmetry of the (111) Cu surface. The step velocity was computed from the shift in apparent terrace widths produced as the tip passes the growth center.
