In laboratory of X-ray spectroscopy we use the soft X-ray excited processes for investigation of the atoms, molecules, thin films, solids and liquids. We study the
- electronic structure of solid materials, thin films, nanoparticles and liquids;
- doping effects in thin oxide films;
- fragmentation of molecules under VUV irradiation;
- ionic liquids and in situ electrochemical processes;
- relaxation and decay processes of soft X-ray created excitations in solids.
- For these studies we use:
- X-ray photoabsorption spectroscopy;
- photoelectron spectroscopy;
- Auger spectroscopy;
- X-ray emission spectroscopy;
- time-of-flight mass spectroscopy;
- photoelectron-photoion coincidence spectroscopies.
For these studies we use synchrotron radiation at different beamlines of synchrotron radiation sources (MAX-lab in Lund, BESSY in Berlin, DESY in Hamburg). Together with three Finnish Universities we have built the FINEST branchline of beamline I3 at MAX-3 storage ring in MAXlab for studies in VUV region. Also we have built the surface science station in our home lab, which basic instrument is photoelectron energy analyser Scienta SES-100. Our present great challenge is the development of the new beamline for soft X-ray studies at MAXlab’s new MAX-4 storage complex.

This equipment also consist of LHe crystate, SEM with resolution 1 um, LEED, time resolved luminescence equipment and sample preparation chamber with three electron gun evaporators.
