Abstract： Monte Carlo simulations have been carried out to investigate the kinetic growth process of ultrathinfilm. It is found that the area of cluster S(t) grows with time t as tk , where growth exponent k is less than 1 when averaged from all clusters. The further results indicate that the cluster growth is nonlinear, i.e., the bigger the cluster area S is, the faster it grows (the larger the k). Similar results also show the fractal dimension D increases with the increasing S. Both the slope a of lgk-lgS and the slope δ of 1gD-lgS are positive and related to the nucleation and growth kinetics.
