Colloidal and micellar approaches to prepare nanostructures

Published on May 11, 2012

Prof. Paul Ziemann describes the basic steps to obtain hexagonally arranged monodisperse metallic nanoparticles on virtually any substrate.

The approach is based on the self-organization of colloids or micelles that are loaded with precursors and combined with specific plasma processes. The size of the resultant nanoparticles is controllable within a certain range. The nanoparticles may then serve as masks for subsequent etching processes transferring the original hexagonal particle pattern onto the substrate as correspondingly ordered arrays of nanopillars or nanopores. Complementary videos show the experimental chemophysical route employed for preparation of nanoparticles as well as the related preparation of magnetic nanoparticles.

Paul Ziemann | University of Ulm, Germany

Prof. Paul Ziemann received his diploma in physics from the Ludwig-Maximilians-Universität München, Germany and his PhD and habilitation from the University of Karlsruhe, Germany. He then worked in the private sector, more specifically in the field of Thin Film Technology & Sensors. He became a professor of physics at the University of Konstanz, Germany in 1987. Since 1995 he has held the Chair in Solid State Physics at the University of Ulm, Germany. He also served as chairman of the Low Temperature Division of the German Physical Society.
His research interests include the properties of metallic nanostructures with an emphasis on transport and magnetic behavior. Furthermore, unconventional nanolithography based on the self-organization of diblock-copolymers and colloids, the preparation of thin films and their properties, the effects of medium-energy ion bombardment, and low-temperature elastic and inelastic tunneling spectroscopy of adsorbed organic molecules complement the research activities. Prof. Ziemann is an Associate Editor of the Beilstein Journal of Nanotechnology.
