Resonance energies and linewidths of Rydberg excitons in Cu${}_2$O 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 $\mu$m for principal quantum numbers up to $…
