Speaker | Prof. Alfred Ludwig, Ruhr-Uni Bochum. Bio: Prof. Dr.-Ing. Alfred Ludwig received his diploma in mechanical engineering from the University of Karlsruhe in 1996 with an emphasis on materials science and microsystem technology. Then he worked in the field of magnetoelastic thin film multilayers at the Institute of Materials Research at the Forschungszentrum Karlsruhe in order to receive his Dr.-Ing. from the University of Karlsruhe in 1999. In June 1999 he joined the caesar research group "Smart Materials" where he focused on the development of high-frequency magnetoelastic thin film materials and devices. From December 2002 to September 2007 he was assistant professor at Ruhr-University Bochum, faculty of mechanical engineering and simultaneously head of the caesar research group “Combinatorial Materials Science”. Since October 2007 he holds a Heisenberg-Professorship for “MEMS Materials” at the Ruhr-University Bochum. He is currently the coordinator of the Research Department “Integrity of Small Scale Systems and High Temperature Materials” at the Ruhr-University Bochum. His research interests include combinatorial and high-throughput methods in materials science, MEMS tools for materials science, nanoscale thin films and multilayers, smart materials (e.g. conventional and ferromagnetic shape memory alloys) as well as new materials for energy conversion and storage. |

New or optimized multifunctional and structural materials are needed, e.g. for miniaturization of technological products with improved functionality even in extreme conditions. For the discovery and optimization of new materials combinatorial and high-throughput experimentation methods as well as dedicated MEMS tools for parallel materials science experiments are very effective. The materials to be investigated are deposited in the form of “materials libraries” by special magnetron sputter deposition methods (co-deposition, wedge-type multilayer deposition, shadow masking). These materials libraries are subsequently processed and characterized by high-throughput experimentation methods (automated EDX, XRD, temperature-dependent resistance and stress screening) in order to relate compositional information with structural and functional properties. The talk will cover examples of the combinatorial development of metallic and oxide materials (e.g. Ni-Ti-X-Y, Fe-W-Ti-O) from binary to quaternary systems, for application areas such as MEMS transducers and solar water splitting. The obtained results are visualized in the form of composition-processing-structure-function diagrams.
