Abstract

The possibility of obtaining core-shell nanoparticles by depositing adatoms of a different element B above a cluster of an element A (system B/A) is studied by Molecular Dynamics simulations. We consider the four cases Ag/Cu, Cu/Ag, Ag/Pd and Pd/Ag, which present very different behaviours, and investigate whether it is possible to build up of well-defined core-shell structures.
