Research Group for Fabrication and Characterization of Nanostructures
We are investigating nanostructures, in particular inorganic materials and carbon, focusing on fabricating novel nanostructures by means of various crystal growth techniques. We utilize advanced electron microscopy and associated experimental techniques to reveal the formation mechanisms and properties of these nanostructures. We are also interested in new phenomena at the nanoscale. |
