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…
Low-frequency Raman scattering in WSe-MoSe heterobilayers: Evidence for atomic reconstruction
Johannes Holler, Sebastian Meier, Michael Kempf +5
We investigate WSe-MoSe heterobilayers with different twist angles between the two layers, by low-frequency Raman scattering. In sufficiently aligned samples with…
Exciton diffusion and halo effects in monolayer semiconductors
Marvin Kulig, Jonas Zipfel, Philipp Nagler +6
We directly monitor exciton propagation in freestanding and SiO2-supported WS2 monolayers through spatially- and time-resolved micro-photoluminescence under ambient conditions. We…
Characterization of highly crystalline lead iodide nanosheets prepared by room-temperature solution processing
Riccardo Frisenda, Joshua O. Island, Jose L. Lado +15
Two-dimensional semiconducting materials are particularly appealing for many applications. Although theory predicts a large number of two-dimensional materials, experimentally only…
Observation of macroscopic valley-polarized monolayer exciton-polaritons at room temperature
N. Lundt, S. Stoll, P. Nagler +10
In this letter, we address the chiral properties of valley exciton-polaritons in a monolayer of WS2 in the regime of strong light-matter coupling with a Tamm-Plasmon resonance. We…
Valley Dynamics of Excitons in Monolayer Dichalcogenides
Gerd Plechinger, Philipp Nagler, Ashish Arora +6
Monolayer transition-metal dichalcogenides (TMDCs) have recently emerged as possible candidates for valleytronic applications, as the spin and valley pseudospin are directly couple…
