Energy states of Rydberg excitons in finite crystals: From weak to strong confinement

PA Belov, F Morawetz, SO Krüger, N Scheuler… - Physical Review B, 2024 - APS
Due to quantum confinement, excitons in finite-sized crystals behave rather differently than
in bulk materials. We investigate the dependence of energies of Rydberg excitons on the …
