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…
Scaling laws of Rydberg excitons
J. Heckötter, M. Freitag, D. Fröhlich +4
Rydberg atoms have attracted considerable interest due to their huge interaction among each other and with external fields. They demonstrate characteristic scaling laws in dependen…
High resolution study of the yellow excitons in CuO subject to an electric field
J. Heckötter, M. Freitag, D. Fröhlich +4
We have used high resolution transmission spectroscopy to study the exciton level spectrum in CuO subject to a longitudinal external electric field, i.e., in the geometry where…
Magnetoexcitons in cuprous oxide
Frank Schweiner, Jörg Main, Günter Wunner +6
Two of the most striking experimental findings when investigating exciton spectra in cuprous oxide using high-resolution spectroscopy are the observability and the fine structure s…
Observation of high angular momentum excitons in cuprous oxide
J. Thewes, J. Heckötter, T. Kazimierczuk +5
The recent observation of dipole-allowed -excitons up to principal quantum numbers of in cuprous oxide has given insight into exciton states with unprecedented spectral r…
