My research group focuses on investigations of key fundamental properties of functional - mostly energy relevant - oxides. In addition to our expertise and traditional focus on ionic conductors, of relevance for applications in, e.g., gas sensors and solid oxide fuel cells, and materials that can store hydrogen, we are becoming increasingly active in the field of luminescence and luminescence materials for solid state white lighting. A unifying theme is to investigate the mechanistic aspects of structural defects and dynamical excitations (local vibrational modes, diffusional motions) on the atomic length scale, and to correlate those elementary materials properties to the functional, macroscopic, properties of the materials. Our research is mainly experimental in nature. The primary tools to this end involve the use of a broad range of neutron scattering techniques (e.g., diffraction, reflection, inelastic and quasielastic scattering), vibrational spectroscopy (Raman and IR), and IR free electron lasers. We are therefore frequent users of instruments available at neutron sources and free-electron laser facilities around the world and to some extent also involved in the development of such methods.
