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…
Wavefunctions and oscillator strengths of Rydberg excitons in cuprous oxide quantum wells
Leon Kühner, Patric Rommel, Jörg Main +2
We investigate the eigenstates, that is, the wavefunctions of Rydberg excitons in cuprous oxide quantum wells and derive expressions relating them to the oscillator strengths of di…
Bound states in the continuum in cuprous oxide quantum wells
Angelos Aslanidis, Jörg Main, Patric Rommel +2
We propose a realistic semiconductor system containing bound states in the continuum (BICs) which allows for a practical realization. By varying the confinement strength of exciton…
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 $…
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…
Linewidths and energy shifts of the electron-impurity resonant states in quantum wells with infinite barriers
Pavel Belov
The linewidths and the energy shifts of the resonant states of the impurity electron in GaAs-based quantum wells (QWs) with infinite barriers are calculated. The two-dimensional Sc…
Excitons in square quantum wells: microscopic modeling and experiment
E. S. Khramtsov, P. A. Belov, P. S. Grigoryev +7
The binding energy and the corresponding wave function of excitons in GaAs-based finite square quantum wells (QWs) are calculated by the direct numerical solution of the three-dime…
