Welcome to the Holleitner group

 

 

The Holleitner group at the Walter Schottky Institute investigates novel types of photo-electronic systems that consist of mixed organic and inorganic nanosystems such as mesoscopic quantum circuits, molecules, nanocrystals, graphene, carbon nanotubes, and photosynthetic "light harvesting" proteins. Such "hybrid nanosystems" can be 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.
One of our main experimental approaches probes the time-resolved optoelectronic transport properties of nanostructures by measuring their photocurrent response in an external electrical circuit with a picosecond time-resolution. The photocurrent signals provide ubiquitous information on excitonic excitations, on charge and heat transfer processes, on spin phenomena as well as on ballistic and quantized optoelectronic transport processes in the nanoscale circuits. Our studies aim to fully exploit the potential of the nanoscale circuits for applications in photovoltaics, as well as communication and information technology.
