Control of island morphology by dynamic coalescence of soft-landed clusters

The deposition of preformed clusters oil surfaces has been established as a now way for growing nano-suctures on surfaces. It has been shown that supp orted island morphology relies on the dynamics of clusters, during the grow th, giving rise to shapes from compact to ramified types. This paper identi fies and discusses, in the. case of antimony cluster deposits, several proc esses responsible for the non-equilibrium island shapes: limited kinetic cl uster aggregation, size dependent coalescence, "wetting-like behavior" of a ntimony clusters on antimony islands. Using successive predetermined cluste r sizes during the deposition process to synthesize polymorphic structure i nvolves the interplay of those mechanisms.
