Title: Monte Carlo Modelling of Nanocluster Growth on Graphene

Abstract: The growth of Au particles on a graphene oxide substrate is examined through the analysis of experimental samples imaged by transmission electron microscopy, and modelling by kinetic Monte Carlo simulation. In order to recover the experimental observed bimodal distributions for island size s, point-island and two-dimensional models were simulated with nucleated islands being allowed to diffuse once they reached a certain size. The model successfully reproduces the bimodal distribution. The diffusion coefficient for these islands was found to be $\sim s^{-1.75}$.
