Center for Materials Research (LaMa)
- Welcome to the web sites of the Center for Materials Research
The Center for Materials research is a core-facility of JLU and supported by the departments of and physics.
It serves for running joint research projects, for the coordination of study programs in materials science and for promoting the qualification of doctoral candidates.
The Center regularly organizes events covering recent issues of materials research. It also offers central experimental resources to its member research groups.

Towards Understanding the Reactivity and Optical Properties of Organosilicon Sulfide Clusters
The optical response of organogtetrel sulfide clusters depends crucially on the ligands. This is demonstrated by the substitution of the phenyl group with naphtyl ligands in the silicon based [(PhSi)4S6] molecular crystal. The adsorption spectra of [(PhSi)4S6] and [(NpSi)4S6] clusters, here calculated within DFT in the independent-particle approximation, are rather different concerning the positions and line shapes of the spectral features. The deviations in the optical response origin from the qualitatively different and differently localized electronic states involved in the transitions resulting in the main spectral peaks of the two compounds. In particular, while HOMO-LUMO transitions are responsible for the first adsorption peak of the [(NpSi)4S6] spectra, they have a minor relevance in the [(PhSi)4S6] spectra.
