Impact of the valence band on Rydberg excitons in cuprous oxide quantum wells
Niklas Scheuler, Jörg Main, Patric Rommel +3
The complex valence band structure of bulk cuprous oxide necessitates going beyond the parabolic approximation to precisely estimate exciton binding energies. The same is true for…

Energy states of Rydberg excitons in finite crystals: From weak to strong confinement
Pavel A. Belov, Florian Morawetz, Sjard Ole Krüger +5
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…

Resonance energies and linewidths of Rydberg excitons in CuO quantum wells
Niklas Scheuler, Patric Rommel, Jörg Main +1
Rydberg excitons are the solid-state analog of Rydberg atoms and can, e.g., for cuprous oxide, easily reach a large size in the region of m for principal quantum numbers up to…
