Milan, 15 February 2021 – Excitons are quasiparticles which can transport energy through solid substances. This makes them important for the development of future materials and devices – but more research is needed to understand their fundamental behaviour and how to manipulate it. Researchers at Politecnico di Milano in collaboration with the Institute of Photonics and Nanotechnologies IFN-CNR and a theory group from the Tsukuba University (Japan) and the Max Plank Institute for the Structure and Dynamics of matter (Hamburg, Germany), have discovered that an exciton can simultaneously adopt two radically different characters when it is stimulated by light. Their work, now published in Nature Communications, yields crucial new insights for current and future excitonics research (click here for the full press release).
