    Roland Bliem

    Postdoctoral Associate

    Education:
    MSc (Physics) and PhD at the Institute of Applied Physics, Vienna University of Technology, Austria

    Roland's research is focused on the surface properties of solid oxide fuel cell cathode materials, in particular Sr-doped LaMO3 perovskites (M=transition metal). He aims to understand the driving forces of segregation processes at these surfaces and relate them to basic surface properties, such as structure, defect concentration, and reducibility. Previous work in the EC interfaces group [Nat.Mater. 15, 1010 (2016)] shows that these basic surface properties can be modified by the deposition of low coverages of metals, influencing the stability of the cathode material. Roland attempts to resolve the origin of the (de)stabilizing effects of these metal species. In parallel, he tests if stabilizing effects observed close to operation conditions can be generalized to include further state-of-the-art perovskite cathode materials.
