Artificial semiconductor nanostructures as well as organic structures with dimensions down to nanometer size have attracted significant attention due to new device applications in photonics, optoelectronics and information technology. The next challenge in this research area is to fabricate and understand hybrid organic/ and plasmonic metal/organic/semiconductor nanostructures where various aspects of the optical and electrical properties may be controlled through active design of these materials.

In my research group we are designing and fabricating such artificial nanostructures and we are trying to better understand the coherent and incoherent relaxation dynamics of excited carriers and excitons in these structures with modern optical investigation methods. The result of our research is not only of fundamental physical interest but is of crucial importance for many potential optoelectronic applications including photovoltaics, lighting, holographic imaging and transformation optics.
