A collaborative research effort by scientists from PDI in Berlin, the Pennsylvania State University, and the New Jersey Institute of Technology has demonstrated the successful growth of high-quality indium selenide (InSe) thin films on semi-insulating gallium arsenide GaAs(111)B substrates using molecular beam epitaxy. This result addresses a very timely challenge in synthesizing InSe with controlled crystalline quality and integrating it with the compound semiconductor platform GaAs, thus opening up new possibilities for high-performance optoelectronic devices, including photodetectors and solar cells.

Dr. Alexander Kuznetsov, a scientist in the Semiconductor Spectroscopy Department at PDI and a member of the Core Research Area Control of Elementary Excitations by Acoustic Fields, has been invited to deliver talks at two internationally recognized conferences in 2025.

Dr. Markus Wagner, head of PDI’s Semiconductor Spectroscopy Department, has been invited to speak at Phononics 2025 in Seoul. The conference brings together international experts to explore cutting-edge developments in phononic materials, phonon transport, and topological phononics.

We're delighted to announce that Master’s student Adriano Notarangelo successfully completed his degree in Solid State Physics and Quantum Technologies, graduating with top honors (110/110 cum laude). Adriano conducted his thesis research at PDI from July 2024 to March 2025, working under the supervision of PDI scientist Philipp John and long-time PDI collaborator Stefano Carlo Cecchi.
