Johannes Reimann (Project B6) receives Poster-Award at ICFSI-16

We congratulate Johannes Reimann, PhD-student in the research group of Prof. Höfer, who received a poster-prize for his outstanding presentation at the 16th International Conference on the Formation of Semiconductor Interfaces (ICFSI-16) in Hannover.

Johannes ReimannIn his contribution, Johannes Reimann presented new insights into the generation and control of spin polarized photocurrents in the Dirac Cone of the topological insulator Sb2Te3 by means of time and angle resolved two-photon photoemission (2PPE). The experimental results allow for a better understanding of the fundamental processes governing the electron dynamics inside the topological surface states of this material class.

The work was undertaken within the DFG priority program "Topological Insulators: Materials-Fundamental Properties-Devices" (SPP 1666) and in close collaboration with project B6 of Prof. Höfer.

ICFSI-16 is part of a biannual conference series primarily focused on phenomena at surfaces, interfaces, and nanostructures that are of strong current interest, ranging from characterization at the atomic scale to prospects of applications.
