Effective interaction dynamics of Rydberg excitons
Binodbihari Panda, Julian Heckötter, Simon Siegeroth +2
Rydberg states of excitons in CuO are known to interact strongly with other carriers in their surrounding such as other excitons, free charge carriers and static charged impuri…

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…
