Breakdown of the static dielectric screening approximation of Coulomb interactions in atomically thin semiconductors
Amine Ben Mhenni, Dinh Van Tuan, Leonard Geilen +10
Coulomb interactions in atomically thin materials are uniquely sensitive to variations in the dielectric screening of the environment, which can be used to control quasiparticles a…
Electrical control of orbital and vibrational interlayer coupling in bi- and trilayer 2H-MoS
Julian Klein, Jakob Wierzbowski, Pedro Soubelet +6
Manipulating electronic interlayer coupling in layered van der Waals (vdW) materials is essential for designing opto-electronic devices. Here, we control vibrational and electronic…
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…
Stark effect spectroscopy of mono- and few-layer MoS
Julian Klein, Jakob Wierzbowski, Armin Regler +5
We demonstrate electrical control of the A-exciton interband transition in mono- and few-layer crystals embedded into photocapacitor devices via the DC Stark effect. Elec…
Photoluminescence and Raman investigation of stability of InSe and GaSe thin films
O. Del Pozo-Zamudio, S. Schwarz, J. Klein +10
Layered III-chalcogenide compounds belong to a variety of layered crystals that can be implemented in van der Waals heterostructures. Here we report an optical study of the stabili…
