Valley-magnetophonon resonance for interlayer excitons
D. S. Smirnov, J. Holler, M. Kempf +8
Heterobilayers consisting of MoSe and WSe monolayers can host optically bright interlayer excitons with intriguing properties such as ultralong lifetimes and pronounced cir…
Electron recoil effect in electrically tunable MoSe2 monolayers
Jonas Zipfel, Koloman Wagner, Marina A. Semina +5
Radiative recombination of excitons dressed by the interactions with free charge carriers often occurs under simultaneous excitation of either electrons or holes to unbound states.…
Interlayer exciton valley polarization dynamics in large magnetic fields
Johannes Holler, Malte Selig, Michael Kempf +11
In van der Waals heterostructures (HS) consisting of stacked MoSe and WSe monolayers, optically bright interlayer excitons (ILE) can be observed when the constituent layers…
Nonclassical Exciton Diffusion in Monolayer WSe2
Koloman Wagner, Jonas Zipfel, Roberto Rosati +9
We experimentally demonstrate time-resolved exciton propagation in a monolayer semiconductor at cryogenic temperatures. Monitoring phonon-assisted recombination of dark states, we…
Non-equilibrium diffusion of dark excitons in atomically thin semiconductors
Roberto Rosati, Koloman Wagner, Samuel Brem +7
Atomically thin semiconductors provide an excellent platform to study intriguing many-particle physics of tightly-bound excitons. In particular, the properties of tungsten-based tr…
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…
