Interaction of Rydberg Excitons in Cuprous Oxide with Phonons and Photons: Optical Linewidth and Polariton Effect
Heinrich Stolz, Florian Schöne, Dirk Semkat
We demonstrate that the optical linewidth of Rydberg excitons in Cu2O can be completely explained by scattering with acoustical and optical phonons, whereby the dominant contributi…

Rydberg excitons in the presence of an ultralow-density electron-hole plasma
J. Heckötter, M. Freitag, D. Fröhlich +7
We use two-color pump-probe spectroscopy to study Rydberg excitons in CuO in the presence of free carriers injected by above-band-gap excitation. Already at plasma densities $ρ…

The phonon assisted absorption of excitons in CuO
Florian Schöne, Heinrich Stolz, Nobuko Naka
The basic theoretical foundation for the modelling of phonon assisted absorption spectra in direct bandgap semiconductors, introduced by Elliott 60 years ago using second order per…
