Signatures of two-photon pulses from a quantum two-level system
Kevin A. Fischer, Lukas Hanschke, Jakob Wierzbowski +5
The theoretical community has found interest in the ability of a two-level atom to generate a strong many-body interaction with light under pulsed excitation. Single-photon generat…
Robust valley polarization of helium ion modified atomically thin MoS
Julian Klein, Agnieszka Kuc, Anna Nolinder +8
Atomically thin semiconductors have dimensions that are commensurate with critical feature sizes of future optoelectronic devices defined using electron/ion beam lithography. Robus…
Direct exciton emission from atomically thin transition metal dichalcogenide heterostructures near the lifetime limit
Jakob Wierzbowski, Julian Klein, Florian Sigger +9
We demonstrate the reduction of the inhomogeneous linewidth of the free excitons in atomically thin transition metal dichalcogenides (TMDCs) MoSe, WSe and MoS by…
Electric-field switchable second-harmonic generation in bilayer MoS by inversion symmetry breaking
Julian Klein, Jakob Wierzbowski, Alexander Steinhoff +8
We demonstrate pronounced electric-field-induced second-harmonic generation in naturally inversion symmetric 2H stacked bilayer MoS embedded into microcapacitor devices. By a…
