Research and teaching in the field of surface and interface physics

Prof. Dr. Johannes Barth

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.

Lecture + Tutorial: Advanced Materials Analysis with Synchrotron Radiation: Techniques and Applications

Lecturer: Dr. Francesco Allegretti (2 hours + 1/week)

The use of photons as primary excitation source offers a variety of tools, which prove invaluable for unraveling the physical and chemical properties of condensed matter and for elucidating the underlying physical processes at the atomic scale. This lecture course provides a comprehensive survey of a suite of experimental techniques that are based on the use of synchrotron radiation. Fundamental principles, modes of operation and basic instrumentation will be presented for each technique, and the potential and value will be illustrated by means of relevant and innovative applications to advanced materials analysis.
