FM 12: German-French Focus Session: Materials Research in Polar Oxides – From Domain Engineering to Photonic and Electronic Devices I

Mittwoch, 11. März 2026, 09:30–13:00, BEY/0138

chair: Simone Sanna (Justus-Liebig-Universität Gießen, DE)
The focus session is dedicated to bridge the gap between materials research in polar oxides and research fields that apply those materials, such as nonlinear and quantum optics, electronics or sensoring, spanning experimental studies and first-principles simulations.
