Physics of Surfaces and Interfaces
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.

- Binding of gaseous compounds on surface supported metalloporphyrin arrays
- For the creation of novel materials and devices, inspiration is frequently sought in nature. Metalloporphyrins are natural compounds and common prosthetic groups to handle respiratory gases, sensing and catalytic functions. Arrays of metalloporphyrin layers under vacuum conditions present a versatile playground for functional interfaces due to the coordinatively unsaturated metal centers. Complexes of inorganic gaseous molecules, as CO, with metalloporphyrins are important intermediate species in catalytic processes, crucial in chemical processing. We aim to improve the fundamental understanding of these complex systems, in order to enable green chemical production. Hence, we perform model experiments with different metalloporphyrins (e.g. ruthenium octaethylporphyrin or ruthenium tetraphenylporphyrin) on different well-defined metal surfaces (e.g. Ag(111) or Cu(110)). Our methods are, on the one hand, visualization of the porphyrin structures on the metal surface with scanning tunneling microscopy (STM) on a submolecular level. To support these data we use spectroscopic methods, such as X-ray photoelectron spectroscopy (XPS). The bachelor thesis would focus on adsorption experiments with CO on metalloporphyrins with STM.
