Generating and assessing data from combinatorial and high-throughput experiments for the design of new materials — •Alfred Ludwig — Institute for Materials, Ruhr-University Bochum,44780 Bochum, Germany — ZGH and MRD, Ruhr-University Bochum,44780 Bochum, Germany

Design of new materials is a key challenge in materials science: e.g. new materials for future energy systems are urgently needed. Thin film combinatorial materials science (CMS) enables an efficient generation of consistent and large datasets on (unexplored) multinary materials, promoting the discovery and optimization of new materials. CMS can also rapidly verify or falsify theoretical or computational materials predictions. CMS comprises fabrication and processing of thin film materials libraries by combinatorial sputter deposition and processing, followed by extensive high-throughput characterization of the thin film samples contained in the libraries. The large datasets which are produced by the combinatorial approach need to be analyzed with new software tools, e.g. for the rapid assessment of X-ray diffractograms, necessary for the mapping of phase diagrams. Obtained results for ternary and quaternary systems are visualized in the form of composition-processing-structure-function diagrams, interlinking compositional data with structural and functional properties. The talk will cover and discuss examples of the combinatorial development of intermetallic materials for shape memory alloys, superalloys and thermoelectric applications as well as the development of metal oxide thin film materials libraries for solar water splitting.
