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) […]

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 […]

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%.

Anisotropic spin and orbital Rashba effect of tellurium atoms on Au(100)
In a collaborative effort with the group of Prof. F. Reinert and Dr. H. Bentmann at University Würzburg the electronic structure of a tellurium (Te) adsorbate structure was investigated by angle resolved photoemission (ARPES, U Würzburg) and structure determination (U Erlangen). It turned out, that even in such a relatively simple surface structure formed by […]

Coverage induced switching of chirality in surface self-assemblies of prochiral molecules
When molecules adsorb on surfaces many interesting phenomena arise. One is the occurrence of chirality (handedness) from molecules that a achiral in the gas phase. These so called “prochiral” molecule can adsorb in two mirror symmetric ways on a surface and become chiral, since the two configurations cannot be superimposed by translation or rotation. By […]

DFG funding: ultra-thin transition metal telluride films
The German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) has awarded funding to the group for the investigation of the growth and structure of ultra-thin transition metal telluride films. Such films find applications as thermoelectrics, sensors, phase-change materials, etc. But more intriguing are properties emerging from the non-trivial topological nature of their band structures particularly in the […]The German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) has awarded funding to the group for the investigation of the growth and structure of ultra-thin transition metal telluride films.
