The deposit of small amount of atoms on well defined surfaces may induce the formation of well organised nanostructures, which can present a long range order. It is the case for example of Co deposit on Au(788) vicinal surface or of Ag deposit on Cu vicinal surfaces. In this context, this thesis presents the study of the Ag/Ni system and more specifically silver adsorption on Ni(111) and Ni(322) surfaces. Silver deposit on the Ni(322) surface induces, after annealing, the formation of facets. The period (which is on the order of some ten of nanometers) and the facets orientations depend strongly on the Ag coverage and on the annealing process. Under particular conditions, the system presents a periodic succession of (211) and (111) facets. ...
