Watching light beams go out

PhD candidate Christian T. Plass looks at a sample with individual nanowires on a thin layer of silicon dioxide on silicon. Only the substrate can be seen, as the nanowires are too tiny.

These results are only possible thanks to the combination of the Extremely Brilliant Source (EBS) beam, the capabilities of ID16B and the new streak camera that the team from the University of Jena installed on the beamline back in 2021. The camera complements the existing set-up of optical luminescence detection on ID16B: "We’ve added one more dimension: time", explains Christian Plass, PhD candidate in Jena and first author of the paper. ...
