Nanoscopic functional cage clusters

This project aims at a wide-ranging characterization of nanometer-sized functional inorganic fullerene- and metal-oxo-based cluster molecules and their aggregates. The targeted molecules are in the focus of interest as molecular building blocks for nanoelectronics and spintronics due to their unique structural, supramolecular, redox, and magnetic properties. Moreover, these features can be synthetically tuned to a large extent. Appl. Phys. A 87 (3), 475 (2007)


Silicon Germanium nanostructures

Self-assembled growth of semiconductor nanostructures is a bottom-up approach to build nanostructures with the help of nature. Recently, nanowires have attracted a lot of interest because they are required to interconnect functional units in nano- and molecular electronics. We found a way of controlled fabrication of Si and Ge nanowires with a width down to 3 nm and a thickness of only one atomic layer (0.3 nm). Phys. Rev. Lett. 98, 166104 (2007)
