The central topic of this research group is the investigation of basic reaction mechanisms at the interface plasma surface. The research on this topics can be summarized by posing two major questions:
The following main research themes are adressed
Reactive plasmas are often used to deposit thin films or to modify surfaces. Important input parameters are the particle fluxes onto the substrate surface and the state of the surface itself. These quantities are measured using mass spectroscops and optical in-situ real time dagnostics.
As novel methods for thin film deposition applications, microplamas at atmospheric pressure are currently under investigation.
The interaction of plasmas with biological systems is studied in detail. By using particle beam experiments, the effects of ions, radicals and phtons on bacteria and biomolecules is studied and isolated.
In a reactive plasma, small particles formed as well as strucures on a growing film surface are formed. This complex structure formation can be controlled by a proper adjustment of plasma parameters.
