Structure and Dynamics in Functional Oxides

​Our research, at the interface between physics, chemistry, and materials science, focuses on the characterization of fundamental properties of functional – mostly energy relevant – oxides. In addition to our traditional focus on solid state proton conductors, which show potential for next-generation solid oxide fuel cells and hydrogen sensors, we are currently also working on other classes of hydrogen containing oxides, such as hydride-ion conductors and materials used to store hydrogen, as well as oxide phosphors for their future application in solid-state lighting devices. A unifying theme of our research is the aim to develop a detailed understanding of the coupling of the materials’ functional properties, such as ionic conductivity and luminescence, to their atomic-scale structure and dynamics, and on this basis, develop strategies for the development of new materials with enhanced performance in certain technological applications. The primary tools to this end involve the use – and to some extent development – of a broad range of vibrational spectroscopy, neutron scattering, and free-electron laser techniques. The group is particularly active in the Swedish and international neutron scattering community and, at present, performs about ten neutron experiments at international large-scale neutron facilities a year. Specifically, we are also becoming increasingly interested in the field of time-resolved experiments based on infrared light as well as on X-rays to study, e.g., the coupling between vibrational dynamics, ionic diffusion, and local structure of materials.
