Thermoelectric materials (RIXS)
In the search for sustainable energy resources and green technologies, thermoelectric materials play an important role. They are characterized by their ability to convert heat directly into electricity or vice versa electrical energy in temperature gradients. By means of RIXS spectroscopy (Resonant Inelastic X-ray Scattering), the influence of the coupling of lattice structure on electronic structure on the thermoelectric performance can be investigated.
RIXS can also be used to study magnetic excitations in a variety of materials, ranging from model materials for basic research to materials with functional energy. It is a complementary technique to the more traditional method of inelastic neutron scattering, and by combining these two methods, a much deeper understanding of the physics of magnetic systems can be achieved.
