Abstract
The uptake of zinc on low index silver and copper surfaces (Ag(100), Ag(110), Ag(111) and Cu(100)) has been studied by AES, TPD and LEED. On the silver substrates, uptake proceeds predominantly by 3D crystallite nucleation: this aggregation is enhanced at elevated temperatures and followed by complete desorption of all the zinc at temperatures just above 500 K. Limited alloying may also occur during extended deposition at elevated temperatures. By contrast, on Cu(100) there is a greater interaction between the zinc and the substrate leading to greater wetting, initial formation of 2D islands and a multistage desorption process extending up to 700 K. No ordered zinc phases were observed on any of the substrates and there is no evidence for significant surface alloying prior to desorption of the zinc.
