Robust excitons across the phase transition of two-dimensional hybrid perovskites

Jonas D. Ziegler, Kai-Qiang Lin, Barbara Meisinger +11

Two-dimensional halide perovskites are among intensely studied materials platforms profiting from solution based growth and chemical flexibility. They feature exceptionally strong…

Twist-angle engineering of excitonic quantum interference and optical nonlinearities in stacked 2D semiconductors

Kai-Qiang Lin, Paulo E. Faria Junior, Jonas M. Bauer +6

Twist-engineering of the electronic structure of van-der-Waals layered materials relies predominantly on band hybridization between layers. Band-edge states in transition-metal-dic…

Large-scale mapping of moiré superlattices by Raman imaging of interlayer breathing mode and moiré phonons

Kai-Qiang Lin, Johannes Holler, Jonas M. Bauer +6

Moiré superlattices can induce correlated-electronic phases in twisted van-der-Waals materials. Strongly correlated quantum phenomena emerge, such as superconductivity and the Mott…

Complete polarization of electronic spins in OLEDs

Tobias Scharff, Wolfram Ratzke, Jonas Zipfel +3

At low temperatures and high magnetic fields, electron and hole spins in an organic light-emitting diode (OLED) become polarized so that recombination preferentially forms molecula…

Floquet spin states in OLEDs

S. Jamali, V. V. Mkhitaryan, H. Malissa +11

Weakly spin-orbit coupled electron and hole spins in organic light-emitting diodes (OLEDs) constitute near-perfect two-level systems to explore the interaction of light and matter…

Picosecond time-resolved antibunching measures nanoscale exciton motion, annihilation, and true number of chromophores

Gordon J. Hedley, Tim Schröder, Florian Steiner +8

The particle-like nature of light becomes evident in the photon statistics of fluorescence of single quantum systems as photon antibunching. In multichromophoric systems, exciton d…
