摘要

The evolution and control of porosity in nanoporous platinum thin films have been studied both experimentally and by means of Kinetic Monte Carlo simulations. Experimentally, the sizes of the pores were controlled by a method of coarsening at different temperatures after dealloying. The KMC simulations also showed similar results which was governed by the temperature dependence of surface diffusion of the platinum atoms in the thin film. Good agreement is found between experimentally observed and simulated results.
