Cluster physics Freiburg

The group does research on clusters, small aggregates (N = 3 or 4 up to several thousands) of atoms or molecules, which are transitional forms of matter between atoms and molecules and their corresponding bulk forms. Properties of clusters are studied as a function of cluster size for fundamental reasons as well as technological reasons: clusters may offer ways to make altogether new kinds of materials.
