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…
Autoionization and dressing of excited excitons by free carriers in monolayer WSe2
Koloman Wagner, Edith Wietek, Jonas D. Ziegler +6
We experimentally demonstrate dressing of the excited exciton states by a continuously tunable Fermi sea of free charge carriers in a monolayer semiconductor. It represents an unus…
Fast and anomalous exciton diffusion in two-dimensional hybrid perovskites
Jonas D. Ziegler, Jonas Zipfel, Barbara Meisinger +7
Two-dimensional hybrid perovskites are currently in the spotlight of condensed matter and nanotechnology research due to their intriguing optoelectronic and vibrational properties…
Bright excitons with negative-mass electrons
Kai-Qiang Lin, Chin Shen Ong, Sebastian Bange +15
Bound electron-hole excitonic states are generally not expected to form with charges of negative effective mass. We identify such excitons in a single layer of the semiconductor WS…
Temporal evolution of low-temperature phonon sidebands in WSe monolayers
Roberto Rosati, Samuel Brem, Raül Perea-Causín +9
Low-temperature photoluminescence (PL) of hBN-encapsulated monolayer tungsten diselenide (WSe) shows a multitude of sharp emission peaks below the bright exciton. Some of them…
Light-matter coupling and non-equilibrium dynamics of exchange-split trions in monolayer WS2
Jonas Zipfel, Koloman Wagner, Jonas D. Ziegler +4
Monolayers of transition metal dichalcogenides present an intriguing platform to investigate the interplay of excitonic complexes in two dimensional semiconductors. Here, we use op…
