Abstract
Scanning tunneling microscopy observations show that steps on vicinal surfaces near (110) missing-row reconstructed surfaces of metals such as Au and Pt tend to form networks. A simple microscopic model introduced here shows that these networks are unstable (or metastable) against faceting. This leads to the formation of ridges between rounded areas and of angles in the equilibrium shape of the (110) facet.Keywords
