Coatings for protective and medical applications

The group focuses on the development of thin films and coatings with properties enhanced by nanoscale effects for technical and medical applications . The coatings are fabricated by classical magnetron sputtering, reactive sputtering, high-impulse magnetron sputtering (HiPIMS) and plasma-assisisted chemical vapour deposition (PACVD). The transfer from lab to applications throught the use of both a medium scale industrial HiPIMS coating system (Ingenia S3p) and lab-scale UHV sputter deposition systems. For the analysis of the films structure and morphology we use XRD, SEM, STEM, and AFM. Chemical properties are assessed by XPS, ToF-SIMS, and RBS. Additional methods such as Kelvin Probe Microscopy, Magnetic Force Microscopy, Piezo Force Microscopy, and ellipsometry are further availbe. The experimental work is complemented by ab-initio and molecular dynamics simulations performed in collaboration with the Empa Modeling group.
