Collaborative Research Center (Sonderforschungsbereich) SFB 1083:
The Collaborative Research Center SFB 1083 of the DFG was established at Philipps-Universität Marburg in 2013. More than 80 chemists and physicists jointly investigate solid/solid interfaces of a variety of organic and inorganic materials in order to achieve a detailed microscopic understanding of the chemical bonding, the electronic coupling, and the dynamics of energy transfer for model systems of different classes of heterointerfaces.
Since 2017 the SFB includes groups from the Universities of Gießen and Münster and the Jülich Research Center.
Peter Jakob and Sebastian Thussing derived ultrafast charge-transfer times at molecule-metal interfaces using the vibrational oscillation period as an internal clock reference Dynamical charge-transfer processes at molecule-metal interfaces proceed in the few fs timescale that renders them highly relevant to electronic excitations in optoelectronic devices. This is particularly true when […]
Andreas Beyer and coworkers achieved the determination and spatial resolution of electric fields at interfaces with the transmission electron microscope. Nanometer-scale built-in electric field are the basis of many modern (opto)electronic devices, such as solar cells, lasers or batteries. Optimization of these devices requires precise characterization of such fields at […]
Robert Wallauer and coworkers combined a high harmonic laser source with an electron momentum microscope to record orbital images of the charge transfer at an organic/metal interface with femtosecond time resolution. The microscopic charge-transfer dynamics across molecular interfaces is reflected in the population of electronic orbitals. These were, for the […]
In a new publication in Chemical Science, projects A2 (Witte) and A4 (Gottfried) report on the intricate desorption characteristics of pentacene (PEN) and perfluoropentacene (PFP) monolayers on the MoS2 surface. Unitary molecular monolayers are thermally stabilized by entropy due to their high mobility rather than the organic/inorganic interface bond, which […]
In a new publication in Organic Electronics, project A2 (Witte) reports on the establishment of a complete high vacuum-based manufacturing and electronic characterization of organic field effect transistors (OFET). The electronic coupling between OSC and metallic electrodes is of key importance for the efficiency of charge carrier injection in organic […]
