Structure of a Zn monolayer on Ag(111) and Ag(110) substrates: an AES, LEED and STM study

Abstract

Auger Electron Spectroscopy, Low Energy Electron Diffraction and Scanning Tunneling Microscopy have been used to study the atomic structure of a Zn monolayer deposited on Ag(111) and Ag(110) substrates at room temperature. On both faces, there is formation of a close packed monolayer of Zn covering the entire substrate surface and giving rise to specific Moir{é} patterns. From a comprehensive LEED and STM data analysis, we deduce that the Zn monolayer adopts a (111) structure equivalent to a pure Zn layer rotated with respect to the silver substrate, of about $1.5^{\circ }$ on the Ag(111) face and of about $4.5^{\circ }$ on the Ag(110) face giving rise respectively to ($\sqrt{156}\times \sqrt{156})R18^{\circ }$ and c(12x6) superstructures.
