Abstract

The fractal growth of 2D thin films on metal surface is studied by means of kinetic Monte Carlo simulation, using realistic growth model and physical parameters. Emphasis is given to time dependence of the size S(t) and branch width b(t) of the island. It is found that the island size S(t) grows with time t as t^k, where growth-exponent k is slightly less than one when averaged from all islands. Similar results for the branch width of islands are also obtained from the simulations are not very low coverage, i.e., b(t) (infinity) t^(alpha ). The kinetic scaling values k and (alpha) of fractal growth of thin films may be helpful to understand the growth mechanism of thin films.
