This is not easy to understand, since on thermodynamic grounds clusters should be less stable than the bulk material. It is possible that clusters generated by electrochemical nanostructuring may undergo a certain degree of alloying with the material of the surface that could increase their stability. Indeed, Monte Carlo simulations show that if achievable, such alloying will improve the stability of the clusters toward dissolution. 

An alternative type of tip-induced nanostructuring has recently been proposed. In this method, a single-crystal surface covered by an underpotential-deposited mono-layer is scanned at a close tip-substrate distance in a certain surface area. This appears to lead to the incorporation of UPD atoms into the substrate lattice, yielding a localized alloy. This procedure works for Cu clusters on Pt(l 11), Pt(lOO), Au(l 11), and for some other systems, but a model for this type of nanostructuring has not been available until now. (Xiao et al., 2003). 

Electrochemical oscillation during the Cu-Sn alloy electrodeposition reaction was first reported by Survila et al. [33]. They found the oscillation in the course of studies of the electrochemical formation of Cu-Sn alloy from an acidic solution containing a hydrosoluble polymer (Laprol 2402C) as a brightening agent, though the mechanism of the oscillatory instability was not studied. We also studied the oscillation system and revealed that a layered nanostructure is formed in synchronization with the oscillation in a self-organizational manner [25, 26]. 

Interesting nanostructures, that may present an interaction among nanoclusters, with consequent increase of local field enhancement factor are obtained by irradiating AuCu alloy clusters with Ne ions at 190 keV [30].
