Structure formation of organic molecules on dielectric surfaces — •William Janke and Thomas Speck — Institut für Physik, Johannes Gutenberg-Universität Mainz, Germany
When buckminsterfullerenes (C60) are deposited upon a substrate by means of molecular beam epitaxy, many different structures can form depending on the substrate in use and the experimental conditions. Calcium fluoride (CaF2) as a substrate is particularly interesting since its interaction with C60 is slightly weaker than the C60-C60 interaction, which leads to very interesting types of two-layered clusters. These clusters and other properties of the C60-CaF2 system have been observed in experiments [1]. To further the understanding of such deposition and diffusion systems, we study the diffusion and self-assembly of C60 on CaF2(111) by means of MD and KMC simulations as well as theoretical considerations to build a comprehensive model for this system.
