Observation of exciton redshift-blueshift crossover in monolayer WS2
Edbert J. Sie, Alexander Steinhoff, Christopher Gies +10
We report a rare atom-like interaction between excitons in monolayer WS2, measured using ultrafast absorption spectroscopy. At increasing excitation density, the exciton resonance…
Plasmonic Superconductivity in Layered Materials
M. Rösner, R. E. Groenewald, G. Schönhoff +3
Plasmonic excitations behave fundamentally different in layered materials in comparison to bulk systems. They form gapless modes, which in turn couple at low energies to the electr…
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…
