  How a Single Titaniumditelluride Layer Grows on Au(111)

  In a detailed work published recently in Phys. Rev. B 113, 195426 (2026) our group resolved the atomic structure of epitaxial single-layer and multilayer TiTe2 films on Au(111), which surprisingly evolve from isolated TiTe2 units with Ti atoms embedded in the topmost gold layer. By Scanning Tunneling Microscopy (STM), Low-Energy Electron Diffraction Intensity Analysis (LEED-IV) […]In a detailed work published recently in Phys. Rev.

  Catching Nanoscale Surface Vibrations with diffused x-ray scattering

  In our study, together with leading groups in Fermi free electron laser in Trieste and other collaborators, we have revealed the possibility of capturing finite momentum surface vibrational modes using diffused extreme ultraviolet light. After a femtosecond laser pulse excites the surface, the diffused x-ray pulse oscillates and reveal the presence of coherent surface waves […]In our study, together with leading groups in Fermi free electron laser in Trieste and other collaborators, we have revealed the possibility of capturing finite momentum surface vibrational modes using diffused extreme ultraviolet light.

  Dark exciton dynamics revealed in single-layer tungsten disulfide

  Our new paper is out! We demonstrate an approach to track in real time the dynamics of a normally invisible excited state in an atomically thin material. In single-layer WS2, electrons and holes bind into excitons. Some exciton states are “bright” and emit light, while others are “dark” and usually cannot be seen, even though […]Our new paper is out!

  Our booth at the Long Night of the Sciences!

  At this years Long Night of the Sciences (Lange Nacht der Wissenschaften) we presented our work to the general public. Hannah, Isabella, Alexander, and Eric showed and explained not only how LEED and STM produce scientific data but also presented real instruments. Video animations, 3D models and posters triggered questions and led to fruitful exchanges […]At this years Long Night of the Sciences (Lange Nacht der Wissenschaften) we presented our work to the general public.

  Molecules on perovskite solar cell materials: Self-assembly and level alignment

  The so-called ‘Perovskite solar cells’ have achieved remarkable efficiency improvements over the past twenty years, reaching up to 25%. This progress is largely attributed to the discovery and optimization of functional layers that interface the perovskite light absorber with the external environment. However, despite these advancements, perovskite solar cells remain confined to laboratory settings yet, […]The so-called ‘Perovskite solar cells’ have achieved remarkable efficiency improvements over the past twenty years, reaching up to 25%.

  Turning noise into insight: Ultrafast pump-probe phase-randomized tomography

  It may sound counterintuitive, but sometimes noise can actually improve a measurement. In the quantum world, the chaotic nature of noise is not just a disturbance, but it carries valuable statistical information about a system’s behavior. Our team has developed a technique that harnesses the intrinsic randomness of light to track quantum fluctuations in materials.
