Abstract:

The morphologic characteristics of the clusters growth were studied by means of the model of self-adjusted growth of clusters under the field of nonhomogeneous potential which was simulated by the field of nonhomogeneous probability-density of the diffusion particles. The effects on the growth form of cluster as well as the field about the depth factorα, sticking coefficient t were investigated. The results show that properties of the field of nonhomogeneous potential are the main factors controlling the geomitrical morphologic characteristics of the clusters growth , the a and t factors have some effects on the action of the field. Theαfactor determines a dense extent and the t coefficient a compact extent for the growth form of cluster.

Key words: Cluster, Field of the nonhomogeneous probbility-density, Self-adjusted growth of cluster
