Forschen am kältesten Punkt von Chemnitz Bei minus 269 Grad Celsius wird an der TU Chemnitz experimentiert – Eine neue Heliumverflüssigungsanlage ist dafür die Voraussetzung

Our new helium liquefier started operation yeterday! Liquid He can cool experiments down to a few Kelvin 🧊 but is both expensive and scarce. Replacing a 30-year old device, the liquefier contributes to a more sustainable way of doing science by recycling used He♻️

We have a big lineup in our colloquium this week. Our colleague Ulrich Schwarz went all in and assembled a set of speakers on a wide range of topics related to his reserch over the years. We'll be hearing about optical stimulation, short-wavelength laser diodes, and surface emitting lasers...

Really looking forward to having Shuxia visit us for the physics colloquium this week. It's always great to hear more about the theory approach to understanding the often surprising behaviour of halide #perovskites.

📢 In tomorrow's Physics Colloquium, we'll be hosting Hermann Kahle from University of New Mexico, who will be speaking on external-cavity surface-emitting lasers - join us for some insights into this exciting technology! Pew, pew!
Tea, coffee, and biscuits will be served from 3.15pm. ⏰

We have another great talk in the @gem-series.bsky.social on offer! Join us tomorrow for Maurizio's presentation on the realm of coating techniques to scale up the fabrication of #perovskite solar cells and modules!

Come join us in culture capital @chemnitz.de

Are you tired of all the spin-coating or eaporation of perovskites or do you really want to hear about some exciting alternatives? Then, join us this Wednesday for Junia's talk on pulsed laser deposition -- Pew pew!

📢📢📢 GEMS speakers for the month of May are here! Join us for the talks by Junia and Maurizio and hear more about the new exciting deposition techniques for halide perovskites. Spin-coating is so last year.. @gem-series.bsky.social #perovskites

This year, we collaborated with the Johanneum Stiftung in Chemnitz to spark enthusiasm for the #MINT area among the next generation of researchers. Together, we assembled robots and created programs to automate their movements 🤖.

This Wednesday in our HypMol seminar -- Anna Krawczuk from Uni Göttingen on 'From molecules to materials: structure-property correlation in functional materials'.
Join us!

If you are interested in novel materials, their synthesis, characterisation, and application - the Advanced Functional Materials master's programme at Chemnitz University of Technology might just be the right thing to do!
Join us in Europe's Capital of Culture 2025.

More info on this can be found via our website: kahmannlab.com/join-us/

1. Photophysics of hybrid perovskite materials and their use in LEDs
2. Synthesis and application of non-toxic CQDs

Major discoveries that shaped today’s world are deeply rooted in physics - lighting, communication, traffic, and many more. But physics is more: From elementary properties of the smallest atomic building blocks to the evolution of galaxies, physical research spans enormous orders of magnitude.

Look what the Easter bunny brought! It's time for another talk on perovskite solar cells - so, join us tomorrow with Oussama ER-RAJI's insights into perovskite/silicon tandem devices.

Our next @gem-series.bsky.social takes place tomorrow! Join us for Muyi's talk on the commercialisation of perovskite LEDs at 5pm Berlin time.
