Epitaxial-Growth Of Au On Ag(110) Studied By Scanning-Tunneling-Microscopy
Résumé
The epitaxial growth of Au on Ag(110) has been investigated by scanning tunneling microscopy up to 3 ML A very consistent `'intermixed Stranski-Krastanov'' growth mode is demonstrated. Below 1 ML the open structure of the (110) surface allows the Au atoms to be incorporated mainly in the second layer. At higher coverages three-dimensional anisotropic islands of gold are observed. The anisotropic shape, the island density and the transition from two-dimensional to three-dimensional growth are discussed.
