Section for Functional Oxides

The Section for Functional Oxides focuses on functional materials based on oxides, with particular emphasis on developing novel materials and design criteria for energy, electronic and information technologies. The research lies at the boundary between physics, chemistry, and materials science. We investigate the coupling of ionic, electronic and phononic properties to the structure and dynamics at the atomic scale. To do this, we combine advanced synthesis techniques with a broad range of characterization techniques.

Our main activities are:

Synthesis and processing of bulk materials, thin films, nanocrystals and systems with reduced dimensionality, e.g. heterostructures.
Advanced characterization of functional oxides, both in and ex situ as well as in operando.
Understanding the relation between nano- and microstructure and the magnetic, electrical, mechanical and chemical properties of materials.
Developing new design strategies for materials and devices with enhanced performance.
In Summer 2022, FOX Researchers organized the OPERA COST ACTION PhD School Modern directions in Epitaxy
