Emergent Trion-Phonon Coupling in Atomically-Reconstructed MoSe-WSe Heterobilayers
Sebastian Meier, Yaroslav Zhumagulov, Matthias Dietl +8
In low-temperature resonant Raman experiments on MoSe-WSe heterobilayers, we identify a hybrid interlayer shear mode (HSM) with an energy, close to the interlayer shear mod…
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…
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…
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…
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…
Spatial extent of the excited exciton states in WS monolayers from diamagnetic shifts
Jonas Zipfel, Johannes Holler, Anatolie A. Mitioglu +9
We experimentally study the radii of excitons in hBN-encapsulated WS2 monolayers by means of magneto-optical reflectance spectroscopy at cryogenic temperatures in magnetic fields u…
