Fabrication and Functionality of Molecular Nanosystems at Interfaces

NST Seminar

Abstract: The utilization and organization of molecular species is an important issue for advancing nanoscale science and underpins the development of novel functional materials. To this end, we explore molecular bonding and assembly at well-defined homogenous surfaces, textured templates, nanoelectrodes and 2-D sheet layers. The developed bottom-up fabrication protocols employ tailored building blocks and exploit both supramolecular engineering and on-surface covalent synthesis. Structure formation, chemical conversions, and electronic and other characteristics are addressed by a multitechnique experimental approach, whereby scanning probe microscopy provides molecular-level insights that are frequently rationalized with the help of computational modeling and X-ray spectroscopy investigations. We work toward a rationale for the control of single-molecular units and the design of nanoarchitectures with distinct functional properties. 

Bio: The research activities of Johannes Barth centers on the fundamental understanding of phenomena at boundary surfaces and the design of functional molecular nanostructures. His work focuses on the control of complex molecules and highly organized supramolecular architectures at the atomic scale. After studying physics at Munich’s Ludwig Maximilian University, Barth received his doctorate in physical chemistry from the Fritz Haber Institute of the Max Planck Society. Prior to his appointment as a full professor at the Technical University of Munich, he taught at the University of British Columbia, where he is currently an adjunct professor.
