Abstract
The cluster growth on two-dimensional square lattice at different temperature is investigated by Monte Carlo simulation, considering the binding energy of substrate, the coupling energy of nearest neighbor particles and a strain field. The simulation shows that, for 400 K ≤ T ≤ 480 K, the average branch width of the fractal cluster is independent to the temperature T, which is almost equal to the diameter of single particle. For 500 K ≤ T ≤ 680 K, however, the branch width increases gradually to 4 with temperature. With T further increases, clusters consist of large number of particles disappear, due to the strong activity of each particle. The coordination number distributions of clusters at different temperature are also studied.
