Abstract: The reaction-limited aggregation mechanism was simulated by Monte Carlo method for different potential barriers in three dimensions. The cluster size distribution can be called and agrees with the experiment result. The effect of potential barrier on the cluster-size dynamic scaling and distribution was studied on the levels of the micro-scope and meso-scope. In addition, the effects of potential barrier on the mean cluster size, the aggregation rate and the aggregation rate constant were studied by using the similar method also.

Key words: Potential barrier, Reaction-limited aggregation, Cluster-size dynamic scaling, Aggregation kinetics, Monte Carlo method
