• Enhanced Circular Dichroism and Polarized Emission in an Achiral, Low Band Gap Bismuth Iodide Perovskite Derivative5. October 2023 - 11:25

  Johanna Heine (A15) and Sangam Chatterjee (B2) successfully prepared a novel iodido bismuthate that shows strong optical activity despite being achiral Lead halide perovskites and related main group halogenido metalates offer unique semiconductor properties and diverse applications in photovoltaics, solid-state lighting, and photocatalysis. Recent advances in incorporating chiral organic cations […]

• 34. Erfinderlabor: Scientific curiosity of the next Generation1. August 2023 - 14:34

  Hessen’s young MINT scientists conduct research on hydrogen and renewable energies within the SFB 1083 and Philipps University Marburg The 34th Inventors’ Lab (Erfinderlabor) of the Center for Chemistry (Zentrum für Chemie, ZFC) has successfully entered its finale. This year’s event was once again organized by the ZFC in cooperation […]

• Measuring spatially-resolved potential drops at semiconductor hetero-interfaces using 4D-STEM– Publication by A5 (Volz) in Small Methods28. May 2023 - 14:07

  The team of project A5 of the SFB successfully measured the potential drop across a hetero interface using four-dimensional scanning transmission electron microscopy Characterizing long-range electric fields and built-in potentials in functional materials at nano to micrometer scales is of supreme importance for optimizing devices. For example, the functionality of […]

• Interface engineering of charge-transfer excitons in 2D lateral heterostructures – Publication by B9 (Malic) in Nature Communications9. May 2023 - 09:27

  In a joined publication, the groups of Ermin Malic, Bernhard Urbaszek and Andrey Turchanin explained the behavior of quasiparticles in composite semiconductor nanosheets The presence of bound charge transfer (CT) excitons at the interface of monolayer lateral heterojunctions has been a topic of debate in the literature. However, unlike interlayer […]

• Electrical control of hybrid exciton transport in a van-der-Waals heterostructure – Publication by B9 (Malic) in Nature Photonics20. April 2023 - 09:46

  A research team including the experimental group of Andras Kis from the EPFL and the theoretical group of Ermin Malic demonstrated electrical control of the hybrid exciton transport in 2D material heterostructures. Interactions between out-of-plane dipoles in bosonic gases enable the long-range propagation of excitons. However, the lack of direct […]
