Description of the System
The so called SoLIAS system is especially designed for the investigation of the solid-liquid interface and offers the possibility to deposit volatile materials on surfaces of interest and freeze them (LN2) in order to make PES or LEED analysis.

Embedding at BESSY II
To keep a high degree of flexibility the SoLIAS system is mounted on a moveable frame to make the attachment to and operation at various beam lines possible. At BESSY II mainly the U49-2/PGM 1 and PM-3 beam lines with photon energies of 90 … 2000 eV und 20 … 1900 eV are used for XPS or UPS experiments with varying excitation energy. In addition to the mentioned PES experiments also x-ray absorption experiments (XAS) are possible to be carried out.
At the moment the SoLIAS system is mainly used for fundamental research on Li-batteries , organic solar cells , semiconductors for water splitting and absorber materials for thin film photovoltaics .
