Researchers from Basel, Bochum, and Copenhagen have
gained new insights into the energy states of quantum dots. They
are semiconductor nanostructures and promising building blocks for
quantum communication. With their experiments, the scientists
confirmed certain energy transitions in quantum dots that had
previously only been predicted theoretically: the so-called
radiative Auger process. For their investigations, the researchers
in Basel and Copenhagen used special samples that the team from the
Chair of Applied Solid State Physics at Ruhr-Universität Bochum had
produced. The researchers report their results in the journal
Nature Nanotechnology, published online on 15 June
2020.
