C04

Project C04 focuses on creating large and consistent datasets for Co-based multinary oxide thin-film systems. To achieve this, combinatorial deposition of thin-film materials libraries combined with high-throughput characterization is used. Depending on the composition, spinel (AB₂O₄) or perovskite (ABO₃) phases form, and the complexity of these libraries can be increased by systematically introducing additional elements such as Fe, V, Mn, Al, Ni, or Mo at the A- and B-sites. Their impact on electrical conductivity, microstructure, morphology, and crystallographic phases – all crucial properties for electrocatalytic applications – is analyzed. The aims of the project are to identify general trend-lines linking composition and structural properties (like phase constitution or morphology) with functional properties (like resistivity or catalytic activity) and to pinpoint the most promising materials compositions and structures for catalytic applications. To investigate the effect of crystallographic orientations, microcrystalline thin films with large grains (micrometer instead of nanometer range) are fabricated for OER measurements using SECCM. Additionally, thin films are prepared for post-processing in the form of flame-based treatment and laser treatment.
