Plastic Crystals



In plastic crystals the centers of mass of the molecules form a regular crystalline lattice but the molecules are dynamically disordered with respect to the orientational degrees of freedom (see figure below). Orientationally disordered crystals are often considered as model systems for structural glasses. It is our aim to investigate the relaxation dynamics focusing on the high-frequency behavior also in this totally different class of glass forming systems.

Amongst others, the investigations in our group include the following materials (click on the names to learn more):
