Colloidal structures on quasicrystalline substrates — •Matthias Sandbrink and Michael Schmiedeberg — Institut für Theoretische Physik 2: Weiche Materie, Heinrich-Heine-Universität Düsseldorf

Colloidal suspensions, dispersions of micro-sized particles in a fluid, are a well known model system in statistical physics. The behavior of such particles on substrates is important for a lot of applications like photonic crystals, colloidal nanofilms, or novel materials with special rheological or frictional properties. As substrate we consider different aperiodic tilings with long-range order. By using Monte-Carlo simulations, we study the growth process of colloidal structures on such quasicrystalline substrates. Our goal is to grow colloidal quasicrystals in a controlled way.
