Various reasons for the appearance of substrate-induced strain in underpotential deposition (UPD) monolayers on strongly attractive substrates are discussed. An expression for the dependence of monolayer compression on underpotential is obtained considering the two-dimensional film as isotropic and elastic. A theoretical model is proposed for the nucleation of the three-dimensional metal bulk phase taking into account the compressive strain of the UPD monolayer. It is shown that previous results from electrochemical measurements for lead deposition on Ag(111) as well as recent experimental data obtained by in-situ X-ray scattering and scanning tunnelling microscopy are in good agreement with the theoretical considerations. |
