Phonon polariton confinement in isotopically pure MOVPE-grown BN triangles
Maximilian Scharpey, Oskar Schröer, Daniel Wigger +5
Phonon polaritons, quasiparticles formed by the resonant hybridization of light and lattice vibrations, exhibit unique properties like the possibility of hyperbolic dispersions. In…
Nanoscale resolved mapping of the dipole emission of hBN color centers with a scattering-type scanning near-field optical microscope
Iris Niehues, Daniel Wigger, Korbinian Kaltenecker +11
Color centers in hexagonal boron nitride (hBN) are promising candidates as quantum light sources for future technologies. In this work, we utilize a scattering-type near-field opti…
In-operando control of sum-frequency generation in tip-enhanced nanocavities
Philippe Roelli, Isabel Pascual, Iris Niehues +2
Sum-frequency generation (SFG) is a second-order nonlinear process widely used for characterizing surfaces and interfaces with monolayer sensitivity. Recently, optical field enhanc…
Percolating Superconductivity in Air-Stable Organic-Ion Intercalated MoS2
Jose M. Pereira, Daniel Tezze, Iris Niehues +12
When doped into a certain range of charge carrier concentrations, MoS2 departs from its pristine semiconducting character to become a strongly correlated material characterized by…
Strain-dependent exciton diffusion in transition metal dichalcogenides
Roberto Rosati, Samuel Brem, Raül Perea-Causín +5
Monolayers of transition metal dichalcogenides (TMDs) have a remarkable excitonic landscape with deeply bound bright and dark exciton states. Their properties are strongly affected…
Thickness determination of MoS2, MoSe2, WS2 and WSe2 on transparent stamps used for deterministic transfer of 2D materials
Najme S. Taghavi, Patricia Gant, Peng Huang +7
Here, we propose a method to determine the thickness of the most common transition metal dichalcogenides (TMDCs) placed on the surface of transparent stamps, used for the determini…
Phonon Sidebands in Transition Metal Dichalcogenides
Dominik Christiansen, Malte Selig, Gunnar Berghäuser +8
Excitons dominate the optical properties of monolayer transition metal dichalcogenides (TMDs). Besides optically accessible bright exciton states, TMDs exhibit also a multitude of…
