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…

Quantum defects of Rydberg excitons in cuprous oxide: A semiclassical spherical model

Jan Ertl, Patric Rommel, Jörg Main

Excitons, i.e. the bound states of an electron and a positively charged hole are the solid state analogue of the hydrogen atom. As such they exhibit a Rydberg series, which in cupr…

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…

Rydberg excitons in cuprous oxide: A two-particle system with classical chaos

Jan Ertl, Sebastian Rentschler, Jörg Main

When an electron in a semiconductor gets excited to the conduction band the missing electron can be viewed as a positively charged particle, the hole. Due to the Coulomb interactio…

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…
