Carbon nano-structures appear in many different forms such as fullerenes, nanotubes, graphene, which are confined to zero, one and two dimensions respectively. They are stable at ambient conditions and exhibit exciting physical and chemical properties such as ballistic charge transport, high mechanical strength and the highest thermal transport known to mankind. In our group we focus on fabricating novel devices and concepts to exploit these properties for applications in ICT, bio-chemistry and renewable energy. Novel ICT devices such transistors, sensors and interconnects shall be realized by the integration of carbon nano-structures with state-of-the-art silicon processing techniques available in CRANN. Furthermore, new concepts for energy harvesting and conversion such as in solar cells and fuel cells on the basis of nano-carbons are investigated.
The research group combines top-down structuring techniques with the in-situ synthesis of novel functional nano-structures. The creation of such hybrid structures is aimed at the fabrication of new adaptive devices based on the bottom up growth of nano-materials with unique functionality. Using the hybrid approach the precession and scaling capabilities of silicon structuring technology can be maintained. We utilise state-of the art lithographic structuring and self-assembly techniques to obtain mesoscopic preforms such as AAO to integrate functional nano-materials. In particular, we aim to implement not only graphitic nano-structures such as carbon nanotubes and graphene but also inorganic/metallic nanowires.
