We are pleased to highlight the Small Structures special collection “Exploiting Dimensionality in Hybrid Metal Halides – Design, Properties, Applications,” co-edited by Simon together with Wouter Van Gompel, Silvia G. Motti and Bowen Yang. The collection brings together contributions exploring how structural and electronic dimensionality can be used to control the properties of hybrid metal […]
Experimental semiconductor physics
Following light through emerging semiconductors
We use optical spectroscopy and microscopy to understand how light interacts with emerging semiconductor materials and how those interactions shape optoelectronic devices.
Research framework
From light to devices
Our work connects measurement, material behaviour and device function as one experimental research chain.
Photophysics
Spectroscopy, microscopy and dynamics reveal where excitations move, interact and recombine.
Materials
Perovskites, organic semiconductors and nanocrystals provide the systems in which those processes unfold.
Optoelectronics
Solar cells, light-emitting devices and photodetectors connect material response to device operation.

KahmannLab in a New Look
A new look for the KahmannLab website Our website has had a substantial overhaul. Over the past week, we have rebuilt large parts of the site to make it easier to navigate, easier to keep up to date, and more representative of the way we actually think about our research. The new version now brings […]
Khadija receives a Mothers in Science travel grant
Khadija Khaled has received a 2026 Mothers in Science Caregiver Travel Grant to support her participation in an international scientific conference.
Farewell to Hayley
Hayley concludes her postdoctoral work in the KahmannLab and returns to the UK for her next chapter.

Group identity
Experiment, interpretation and a shared lab
Our approach combines hands-on optical measurements and materials work with data processing, theory and modelling. The group brings those perspectives together around the same scientific questions.
