Abstract

A two-dimensional growth model is introduced in which the morphology of aggregates depends on long-range two-body attractive interactions with a potential of the kind U(r)=C/rα. Its relation with continuum diffusive models is discussed. The morphology changes are studied for clusters of 2000 particles as a function of the potential parameters p = C/k_BT < 0 and α. The effect of anisotropy is taken into account by letting particles diffuse and aggregate on a triangular lattice. Tip-splitting occurs for small \p\ and large α. The cluster scaling and symmetry properties are investigated in connection with the morphology transitions.
