The influence of the surface morphology on the local interactions of a one monolayer confined Ni film with a √3-Ag/Si(111) interface with three-dimensional submicron-sized Ag islands has been studied by synchrotron radiation photoelectron spectromicroscopy with a lateral resolution of 120 nm. The spatially resolved two-dimensional maps and the photoelectron spectra measured after Ni post-deposition at 300 K and following step annealing to 970 K give evidence for the different chemical transformation of the coexisting phases. The formation temperature and the stability of the mixed phases have been deduced and discussed.
