Nonlinear Rydberg exciton-polaritons in CuO microcavities
Maxim Makhonin, Anthonin Delphan, Kok Wee Song +13
Rydberg excitons (analogues of Rydberg atoms in condensed matter systems) are highly excited bound electron-hole states with large Bohr radii. The interaction between them as well…
Neutralization of impurities by cw-excitation of high- Rydberg-excitons
Julian Heckötter, Binodbihari Panda, Katharina Brägelmann +1
We investigate the neutralization of charged defects in a CuO crystal experimentally with a cw two-color pump-probe setup. We demonstrate that the excitation of high-lying Rydb…
Taming Charged Defects: Large Scale Purification in Semiconductors using Rydberg Excitons
Martin Bergen, Valentin Walther, Binodbihari Panda +4
We investigate the interaction between highly excited Rydberg excitons and charged impurities in the semiconductor Cuprous Oxide. We find that it is long-ranged and based on charge…
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…
