New paper on LEDs and Phonotic engineering
13-July-2024. We are happy to announce the publication of a new work on the directionality of light emission in perovskite LEDs!
Published in Nature Communications and led by Zher Ying Ooi in Cambridge, the paper highlights how photonic engineering permits to change the directionality of light emission in PL and EL experiments. Great team effort coordinated by Miguel Anaya and Sam Stranks.
KahmannLab at ICSM24
29-June-2024. This week, Simon and Shenyu attended the International Conference on Science and Technology of Synthetic Electronic Materials – great new insights and a great experience staying in beautiful Dresden.
PhD Position Available!!
21-June-2024. We have an open position for a doctoral project entitled Photophysics of organic-inorganic materials for light-emitting diodes starting in September 2024. Check out the official job add to learn more! Deadline 19 July (scroll down for the English verison).
Shenyu visits us for ICSM
20-June-2024. Shenyu is normally based over in Cambridge working in the group of Sam Stranks. Since she will attend next week’s ICSM conference in Dresden, she also joins us in Chemnitz to take the obligatory visitor selfie.
Farewell to Federico
31-May-2024. This week, we had to say ‘Ciao!’ to visiting student Federico. After a combined six months with us, Federico is returning to Cagliari to finish his PhD later this year. We are sad to see you go, Federico, and wish you all the best in the future!
KahmannLab @ the Sino-German PV Workshop
22-May-2024. This week Arina, Mengru, and Simon went to Erlangen to attend the Sino-German Workshop on Printable Photovoltaics hosted by the Friedrich-Alexander University Erlangen-Nuremberg. Besides a lot of interesting talks, the workshop also contained a poster session, lab tours, and a visit to the local Bergkirchweih festival.
New Group Picture
30-April-2024. It has almost been a year since our official start at Chemnitz Univeristy of Technology – time for our first official group picture! Joining Simon are local PhD students Arina and Mengru, who hold Shenyu (joning us from Cambridge), and our guest from Cagliari, Federico.
External Students of The Group
23-April-2024. Our curiosity does not end at our doorstep. This is why we are happy to be involved in student projects at external institutes. This term, we are happy to have two of them to work on exciting projects:
Donyang Liu works on perovskite solar cells at the Institute for Solar Energy Research in Hamelin with Felix Haase. And Martin Ernst conducts a projeect on carbon nanotubes and their treatment at the Fraunhofer ENAS with Martin Hartmann.
Building a new Home
17-April-2024. Our new laser will need a safe home. Our lab is thus back to undergoing construction, and we’ll get a laser-safe and light-tight compartment for our femtosecond spectroscopy/mmicroscopy set-up.
Funding success!!
11-March-2024. We are delighted to announce the positive review of our first research proposal! As part of the DFG scheme for scientific instruments, we shall be receiving a femtosecond laser system and a fast camera for time-resolved spectroscopy and microscopy. Hooray!
Simon Appointed 'Vertrauensdozent' by Friedrich-Ebert Stiftung Foundation
09-February-2024. The Friedrich-Ebert Foundation promotes democracy, political
education, and supports students of outstanding intellectual abilities
and personality on their path through university. Simon will contribute to the Foundation’s work in the field of natural sciences.

20-November-2023. Another permanent member joined our group. Arina Narudin has made the large step stop from Brunei to work with us in Chemnitz on perovskite-inspired materials and their photophysics.
Welcome, Arina!
Federico visits the KahmannLab!
6-November-2023. We are very happy to be hosting Federico Pitzalis from the University of Cagliari for a few months. Federico is a doctoral student supervised by Andrea Mura on the beautiful island of Sardinia and joins us for a project on carrier diffusion in 2D perovskites.
Ciao Federico! We hope you enjoy your stay with us!
Mengru Sun joins the KahmannLab!
17-October-2023. We have a new addition to the KahmannLab! Having graduated from Göttingen University with a degree in physics, Mengru joins us as the first doctoral student in Chemnitz, where to work on spectroscopy and microscopy of solution-processed semiconductors.
Welcome, Mengru – it is great to have you with us!
Winter is coming!
9-October-2023. This week, lectures are starting at Chemnitz University of Technology and we are right in the thick of it.
On Wednesday the new master-level course ‘Halide Perovskites in Optoelectronics’ will start for students of the AFM, physics, or chemistry programme. See you there!
2 PhD positions starting October 2023
11-July-2023. We have two openings for PhD students starting with us at Chemnitz University of Technology in October 2023.
One postion will focus on optical spectroscopy/microsocopy of solution-processed semiconductors & the other one will be on synthesis of perovskites and perovskite-inspired materials.
Find the official advertisements on TUC webpage (here, and here) & submit your application documents in a single .pdf to our secretary Jane quoting the references given in the ads.
