Department Dynamics and Transport in Quantum Materials

Department

The mission of our department "Dynamics and Transport in Quantum Materials" (QM-ADT) is to apply neutron and photon scattering techniques to investigate the dynamic interplay of quasi-particle and charge transport in novel materials for energy conversion. A particular research focus is the study of highly efficient thermoelectric materials. We investigate structure-property relationships bridging from microscopic structure and dynamics to macroscopic thermoelectric properties. Basic research on the interaction processes at the level of elementary excitations in the solid state and thus access to the meV to µeV energy resolution scale is key to a fundamental understanding of transport phenomena in any solid. This knowledge in turn is a necessary prerequisite for optimized design strategies for materials with low thermal conductivity but high electrical conductivity and thermopower.  The suppression of phonon propagation on all length scales ranging from interatomic distances in crystalline structures to the nanoscale responsible for reducing thermal conductivity is the overarching theme of our research.
