Interaction between Rydberg Excitons in Cuprous Oxide Revealed through Resonant Second Harmonic Generation
Andreas Farenbruch, Henje Stolz, Peter Grünwald +5
We report experimental and theoretical investigations of interacting excitons of the yellow series in cuprous oxide (CuO) with principal quantum numbers up to by means of secon…
Emergence of Propagating Exciton-Polaritons in Hybrid Waveguide-van der Waals Heterostructures
Alina Schubert, Karoline Becker, Andreas Thies +7
Integrating few-layer materials into photonic circuits is a promising concept for novel on-chip photonic applications. We incorporate transition metal dichalcogenides (TMDs) with f…
Scrutinizing the Debye plasma model: Rydberg excitons unravel the properties of low-density plasmas in semiconductors
Heinrich Stolz, Dirk Semkat, Rico Schwartz +5
For low-density plasmas, the classical limit described by the Debye-Hückel theory is still considered as an appropriate description even though a clear experimental proof of this p…
Dielectric response of electron-hole systems. Nondegenerate case and quantum corrections
Dirk Semkat, Heinrich Stolz, Wolf-Dietrich Kraeft +1
Analytical results for the dielectric function in RPA are derived for three-, two-, and one-dimensional semiconductors in the weakly-degenerate limit. Based on this limit, quantum…
Coherent transfer matrix analysis of the transmission spectra of Rydberg excitons in Cuprous Oxide
Heinrich Stolz, Rico Schwartz, Julian Heckötter +4
In this study we analyze the transmission spectrum of a thin plate of Cuprous Oxide in the range of the absorption of the yellow exciton states with the coherent transfer matrix me…
Interaction of charged impurities and Rydberg excitons in cuprous oxide
Sjard Ole Krüger, Heinrich Stolz, Stefan Scheel
We investigate the influence of a static, uncorrelated distribution of charged impurities on the spectrum of bound excitons in the copper oxide CuO. We show that the s…
