Hybrid Nanosystems

 

 

 

We investigate photo-electronic systems that consist of mixed organic and inorganic nanosystems such as single molecules, nanocrystals, graphene, carbon nanotubes, and photosynthetic "light harvesting" proteins. Such "hybrid nanosystems" are constructed by combining sophisticated nanofabrication techniques such as chemical functionalization and self-organization with state of the art top-down nanolithography methods such as electron beam lithography and focused ion beam writing.
