【 摘 要 】

We show that mean field rate equations (MFRE) for submonolayer growth with hit and stick aggregation can successfully predict the island size distributions (ISDs) in the precoalescence regime if the full dependence of capture numbers on both the island size and the coverage is taken into account. This is demonstrated by comparison of the integrated MFRE with results from extensive kinetic Monte Carlo simulations. The attempt to use various simplified expressions for the capture numbers in the integration of the MFRE turns out to be insufficient to yield a good description of the ISD.
