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.
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.

Farewell to Hayley
Hayley concludes her postdoctoral work in the KahmannLab and returns to the UK for her next chapter.
Çağlar completes his research project
Çağlar presented the photocurrent microscope that he designed and assembled for high-resolution stage-scanning measurements.
KahmannLab at MATSUS Spring 2026
The group spent a week at MATSUS Spring in Barcelona, exchanging ideas with colleagues and developing new collaborations.
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.
