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…
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…
Intervalley Scattering of Interlayer Excitons in a MoS/MoSe/MoS Heterostructure in High Magnetic Field
Alessandro Surrente, Lukasz Klopotowski, Nan Zhang +9
Degenerate extrema in the energy dispersion of charge carriers in solids, also referred to as valleys, can be regarded as a binary quantum degree of freedom, which can potentially…
Site-selective measurement of coupled spin pairs in an organic semiconductor
Sam L. Bayliss, Leah R. Weiss, Anatol Mitioglu +14
From organic electronics to biological systems, understanding the role of intermolecular interactions between spin pairs is a key challenge. Here we show how such pairs can be sele…
Zeeman Splitting and Inverted Polarization of Biexciton Emission in Monolayer WS2
Philipp Nagler, Mariana V. Ballottin, Anatolie A. Mitioglu +8
We investigate the magnetic-field-induced splitting of biexcitons in monolayer WS using polarization-resolved photoluminescence spectroscopy in out-of-plane magnetic fields up…
