The epitaxial growth of Mg adlayers deposited on Pd(100) and Ag(100) has been studied by Spot Profile Analysing Low Energy Electron Diffraction (SPA-LEED). Above room temperature Mg grows with c(2×2) structure on both substrates in the submonolayer range. Attenuated intensity oscillations of the (00) beam observed for this temperature range demonstrate that the Mg film grows in the multi layer growth mode at low temperature. For Pd(100) oscillations have been found up to 450K. On the other hand measuring simultaneously the specular (00) and the (1/21/2) spot shows that the growth mode changes for Mg/Ag(100) with increasing temperature. For intermediate temperatures Mg forms 3D islands on top of a pseudomorphic layer while Mg desorbs even from the pseudomorphic layer for high temperature deposition. Therefore, we observe an equilibrium between adsorption and desorption of Mg atoms under growth conditions.
