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…
