Diffusion and growth of metal clusters in nanocomposites: a Kinetic Monte Carlo study — •Lasse Rosenthal¹, Alexei Filinov¹, Michael Bonitz¹, Vladimir Zaporojtchenko², and Franz Faupel² — ¹Institut für Theoretische Physik und Astrophysik, CAU Kiel, Leibnizstrasse 15, 24098 Kiel — ²Institut für Materialwissenschaft - Materialverbunde, CAU Kiel, Kaiserstrasse 2, 24143 Kiel

Metallized polymers offer a broad range of applications in many fields of technology[1], including optical and electronic devices and magnetic recording media. Here we present a Kinetic Monte Carlo approach to simulate the coupled processes of diffusion and growth of metal clusters in nanocomposites[2]. Special emphasis is placed on the cluster growth, cluster size distribution and the penetration of clusters into the polymer matrix under different deposition conditions (deposition of metal atoms on a polymer surface and co-deposition of metal and polymer). Furthermore we also present preliminary results of the simulation of the self-organization of nanocolumns[3] during the co-deposition of metal atoms and the polymer matrix.
