Research Topics and Projects
Introduction to various research projects and topics of our group.Tribology
In close collaboration with the Austrian Center of Competence for Tribology we research tribologic films formed from additives using various surface sensitive analytical techniques like electron spectroscopy for chemical analysis, auger electron spectroscopy and atomic force microscopy. In order to produce those tribologic films we use tribometers with a special fluid cell attached, where we can use the sample holders for the electron spectrometer as support for the tribological pairings.
PACVD and Ellipsometry
Plasma-assisted chemical vapour deposition as well as plasma nitriding lack of an on-line process control. Therefore, we investigate the possibilities of spectroscopic ellipsometry for monitoring of surfaces under plasma treatment.
MOventum Vector Electron Spectroscopy (MOVES)
A novel experimental setup for measuring momentum vectors of electrons being emitted from well defined solid surfaces under the impact of energetic electrons or ions (”MOmentum VEctor Spectroscopy - MOVES”) is designed. The application of MOVES can facilitate the theoretical understanding of basically interesting and practically important phenomena as secondary electron emission, ion-induced potential and kinetic emission.
Simulation of Electron Spectra for Surface Analysis (SESSA)
SESSA is a unique tool for researchers active in the field of surface and interface analysis. It allows a user to retrieve data relevant for a specific electron spectroscopy experiment in a matter of a few mouseclicks and, in addition, it provides simulated spectra that can be compared with experimental data to gain information on the specimen structure.
Interaction of beryllium with hydrogen plasma - nuclear fusion first wall investigations
In view of its role as probable first wall material for nuclear fusion devices, several aspects of the behaviour of beryllium in hydrogen plasma at elevated temperatures still need to be investigated. We are concentrating on the oxidation of beryllium in such an environment and its influence on the retention of hydrogen in the bulk.
Analytical Micro-plasmas
We are developing plasma cells integrated into micro-fluidic devices for Lab-on-Chip applications in cooperation with CASECT Ltd. and R.I.C.. These are to be applied as sensitive detectors for gas chromatographs and similar analytical equipment.
PARASOL
Thin film growth and surface erosion: Both processes are based on particles impacting on a surface. In surface erosion typical particle energies are keV. In thin film formation the energy is mostly thermal, even in cases of ion assisted or sputter deposition also energetic particles will hit the surface. Thus both processes can be studied by the Molecular Dynamics (MD) technique.
