KFM 18: Materials Research in Polar Oxides: Perspectives for Optics & Electronics

Thursday, March 20, 2025, 15:30–17:45, H9

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. The goal is to improve the mutual understanding of each other research goals and necessities. Examples for topics could be improved or novel techniques for domain engineering, which are relevant for (nonlinear) optical applications, the growth of novel polar oxides with improved properties over traditional materials, such as higher temperature stability or improved nonlinear characteristics, or the discussion of novel emergent properties in this context, like conductive domain walls in opto-electronical applications.
