2 Post-doc research positions “Plasma interaction with thin film materials for extreme UV”

University of Twente is looking for two motivated and skilled post-doctoral researchers to carry out advanced physics research on understanding the interaction of hydrogen based plasma with thin films used for extreme ultraviolet (EUV) optics applications.

The main aim of the first project is to develop understanding how uptake and diffusion of hydrogen can be monitored in-situ, under realistic test conditions. This project will involve collaboration with the Technical University Delft to study hydrogen uptake in materials with in-situ neutron scattering.

The second project focuses on hydrogen plasmas that contain small amounts of reactive molecules as water or nitrogen. Our aim is to understand in detail how processes as ballistic impact, reaction probabilities and ion penetration depend on type and energy of ions in the plasma, as well as on the composition of the thin film sample.
