Local tuning of Rydberg exciton energies in nanofabricated Cu2O pillars
Communications Materials (2024)
Rydberg excitons in cuprous oxide feature giant optical nonlinearities that may be exploited in quantum applications if suitably confined. Here, the authors show how exciton confinement can be realised by focused-ion-beam etching of Cu2O crystals without noticeable degradation of excitonic properties.
