The structures of various Ag overlayers on the Si(111) surface have been analyzed by impact-collision ion scattering spectroscopy (ICISS) using a beam of Li+ ions of ≈ 1 keV. The Ag overlayers include (i) Ag crystallites deposited at room temperature, (ii) Ag atoms at the Si(111)-(√3×√3)Ag surface, (iii) Ag atoms at the Si(111)-(3×1)Ag surface, and (iv) a (111) epitaxial film of Ag with a thickness of ≈ 20 A ̊.
