Key Areas
- Laser-aided trace gas analysis
- Sensitive (ppbv) and selective detection of molecular species (such as air pollutants) with tunable lasers (diode lasers; optical, parametric oscillators) using photo-acoustic detection methods
- Laser-aided analysis of mechanical film and material attributes
- Determination of linear elastic attributes (using Young’s Module and Poisson’s Ratio, for example) and non-linear material attributes (such as break resistance) with laser-stimulated linear and non-linear surface wave pulses
- Laser-stimulated desorption, ablation and modification
- Surface purification, erosion and modification (structuration) with UV- und VUV-lasers, detection of adsorbates, reaction and erosion products using thermal and laser-stimulated UHV mass spectrometry
- Surface diagnostics (spectroscopy and chemistry)
- In-situ and real-time analysis of surface reactions (such as oxidation of silicon) and growth processes using FTIR spectroscopy (bonding complexes) and spectroscopic VIS-UV ellipsometry (film thickness, for example)
