Exciton and trion dynamics in atomically thin MoSe2 and WSe2: effect of localization
D. Schmidt, T. Godde, J. Schmutzler +9
We present a detailed investigation of the exciton and trion dynamics in naturally doped MoSe2 and WSe2 single atomic layers as a function of temperature in the range 10-300K under…
Experimental realization of a polariton beam amplifier
Dominik Niemietz, Johannes Schmutzler, Przemyslaw Lewandowski +8
In this report we demonstrate a novel concept for a planar cavity polariton beam amplifier using non-resonant excitation. In contrast to resonant excitation schemes, background car…
All-optical flow control of a polariton condensate using non-resonant excitation
Johannes Schmutzler, Przemyslaw Lewandowski, Marc Aßmann +6
The precise adjustment of the polariton condensate flow under incoherent excitation conditions is an indispensable prerequisite for polariton-based logic gate operations. In this r…
Nonlinear spectroscopy of exciton-polaritons in a GaAs-based microcavity
Johannes Schmutzler, Marc Aßmann, Thomas Czerniuk +4
We present a systematic investigation of two-photon excitation processes in a GaAs-based microcavity in the strong-coupling regime. We observe second harmonic generation resonant t…
Influence of interactions with non-condensed particles on the coherence of a 1D polariton condensate
Johannes Schmutzler, Tomasz Kazimierczuk, Ömer Bayraktar +6
One-dimensional polariton condensates (PoCos) in a photonic wire are generated through non-resonant laser excitation, by which also a reservoir of background carriers is created. I…
Low-temperature photocarrier dynamics in monolayer MoS2
T. Korn, S. Heydrich, M. Hirmer +2
The band structure of MoS strongly depends on the number of layers, and a transition from indirect to direct-gap semiconductor has been observed recently for a single layer of…
