Ferroelectricity and Coupled Phenomena Across Multiple Scales

Ferroelectricity provides a uniquely powerful platform for coupling electric, mechanical,
magnetic, and thermal functionalities in functional materials. From multilayer ceramic
capacitors and micro-electro-mechanical systems to CMOS-compatible ferroelectric thin
films and emerging electronic and photonic device architectures, polarization-driven
phenomena already underpin key technologies, while simultaneously posing fundamental
challenges related to complexity and scalability. This Wilhelm and Else Heraeus Seminar
focuses on ferroelectricity as an enabling order parameter for coupled ferroic functionality
across multiple length scales – from fundamental symmetry-breaking mechanisms to
microstructural complexity and device-level implementation. Emphasis is placed on the
role of microstructure, defects, interfaces, and processing as active control parameters,
as well as on emerging data-driven and AI-assisted approaches that support materials
discovery and functional optimization. By bringing together researchers working on bulk
materials, thin films, device physics, theory, and advanced characterization, the seminar
aims to consolidate key physics concepts, bridge disciplinary boundaries, and identify
common challenges and future directions that will shape ferroelectric and ferroic materials
research over the next decade.

The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.
