Research and teaching in the field of surface and interface physics
Research at E20 aims at the fundamental understanding of interface phenomena and their control for the design of functional nanoarchitectures in reduced dimensions. We investigate and manipulate individual nano-objects and highly organized supramolecular systems. Utilizing scanning probe microscopy tools we examine the interior of complex molecules and develop self-assembly protocols for nanotextured surfaces. With advanced spectroscopy techniques we study charge transfer and electronic reconfiguration processes at ultimate temporal resolution. These activities promote the development of novel bottom-up fabrication methodologies and the molecular-level engineering of materials with tailored properties.
