The adsorption of germanium on Ag(1 1 0) has been investigated by scanning tunnelling microscopy (STM), as well as surface X-ray diffraction (SXRD). At 0.5 germanium monolayer (ML) coverage, Low Energy Electron Diffraction (LEED) patterns reveals a s

At room temperature, the early stages (submonolayer) of silicon (Si) deposition onto the anisotropic Ag(110) surface lead to the formation of flat-lying, individual Si nanostripes, with a high aspect ratio, all oriented along the Ag[-100] direction.

The deposition of $1∕3$ Pb monolayer at room temperature onto Ag(111) leads to a $(\sqrt{3}\ifmmode\times\else\texttimes\fi{}\sqrt{3})R30\ifmmode^\circ\else\textdegree\fi{}$ superstructure. We present here a detailed structural study of this surfac
