Research published in the Advanced Functional Materials Journal

The member of our Department of Systems and Control, Tomaž Kos, is co-authoring a recent research published in Advanced Functional Materials Journal.

Researchers from the Electronic Ceramics Department of the Jožef Stefan Institute (JSI), along with the collaborators from the Department of Systems and Control, JSI, the Department of Materials Chemistry of the National Institute of Chemistry in Ljubljana, the North Carolina State University, USA, and the Swiss Federal Institute of Technology in Lausanne, published their findings on the electromechanical response of relaxor ferroelectrics.

The study reveals a unique dynamic response of these relaxor materials to external fields, reflecting their complex structure in terms of the hierarchical texture of ferroelectric domains on top of the disorder at the atomic scale, both of which strongly affect the mobility of the domain walls. The findings of this study open the doors to the design of new, highly performant functional materials by multiscale structural design.

The researcher 's contribution was in the field of development of the measurement system for harmonic analysis of the materials and development of the measurement systems for piezoelectric and dielectric measurements.
