Solid State and Inorganic Materials Chemistry

The main focus of my research lies in the field of experimental and theoretical chemistry of solid state compounds and inorganic materials such as mixed main group metal / transition metal cluster compounds and complex transition metal oxides. This includes the preparation and characterisation of novel tin, antimony and lead cluster compounds with promising materials properties and the calculation of band structures of solid state compounds to investigate the crystal structure and the electronic structure. For the preparation of these compounds quite a number of different methods will be used, from classical high temperature sintering in evacuated quartz tubes for the synthesis of pure powder materials, to the crystallisation from metal melt, or even gas phase reactions (chemical transport reactions) for the preparation of single crystals. For the identification of these compounds we use X-ray single crystal or powder diffraction, Mössbauer spectroscopy, electron spin resonance, energy dispersive X-ray spectrometry (EDX), high resolution electron microscopy (HREM), transmission electron microscopy (TEM), measurements of temperature dependence of the magnetic susceptibility and the electrical resistance.

This work involves a large number of national and international co-operations with research groups on the different topics in inorganic materials and theoretical chemistry.
