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…
Revealing the nature of excitons in liquid exfoliated monolayer WS2
Ł. Kłopotowski, C. Backes, A. A. Mitioglu +6
Transition metal dichalcogenides hold promise for applications in novel optoelectronic devices. There is therefore a need for materials that can be obtained in large quantities and…
