Morphology transitions in the growth of domains in surfactant monolayers

Results of extensive computer simulations of domain growth are presented. The simulations are able to reproduce the tip-splitting transition observed in real systems including surfactant monolayers at the air-water interface. In the transition region clusters with hybrid morphologies appear. The presence of such hybrid clusters seems to suggest that, at least in the case of our simulation, there is a gradual cross-over from dendritic to tip-splitted clusters as the lateral coupling beta J varies through the transition region
