Title: Simulation on fractal growth in ultra-thin films
Abstract: The growth of fractal mrophology in ultra thin films has been simulated by supposing various cluster diffusion steps and the rotation of clusters.In contrast to DDA(Deposition Diffusion Aggregation)model,we find that the rotation of the clusters results in accelerating aggregation of the clusters.At the same time We calculate the fractal dimensions of the fractal morphology and find that it posses fractal properties with a fractal dimension D=1.50-1.71.The results agrees well with the result of D=1.68~1.79 with DDA model.It indicates that the effect of the rotation agrees with the effect of the diffusion of the clusters.The morphology can be obtained only by supposing rotation of the clusters.
