Self-assembly and Nanostructures

In nanostructured materials intriguing electrical and optical properties are observed due to quantum phenomena. The properties are tunable and enable novel applications.

One of the challenges of nanotechnology is the control of the spontaneous organization of molecules into aggregates with new functionalities that can be integrated into devices. We investigate different aspects of the self-assembly of cyanine dye molecules during film formation from solution (spin coating). The dye molecules are an interesting model system as we can induce both, J- and H-aggregates as well as the growth of large single crystals in thin films.
