Mismatch between Raman shear modes and ferroelectric polarization in 3R-MoS
Johannes Schwandt-Krause, Jan-Niklas Heidkamp, Mohammed El Amine Miloudi +7
Sliding ferroelectricity in parallel-stacked two-dimensional van der Waals materials enables a broad range of novel device concepts, but exploiting it requires reliable, non-destru…
Emergence of Propagating Exciton-Polaritons in Hybrid Waveguide-van der Waals Heterostructures
Alina Schubert, Karoline Becker, Andreas Thies +7
Integrating few-layer materials into photonic circuits is a promising concept for novel on-chip photonic applications. We incorporate transition metal dichalcogenides (TMDs) with f…
Unlocking klockmannite: formation of colloidal quasi-2D CuSe nanocrystals and photo-physical properties arising from crystal anisotropy
Urvi Parekh, Nadiia Didukh, Samira Dabelstein +8
Copper selenide is an exceptional quasi-layered monolithic material that exhibits both semiconducting and metallic properties in adjacent visible and near-infrared (NIR) spectral r…
Investigating the Ferroelectric Potential Landscape of 3R-MoS through Optical Measurements
Jan-Niklas Heidkamp, Johannes Schwandt-Krause, Swarup Deb +4
In recent years, sliding ferroelectricity has emerged as a topic of significant interest due to its possible application in non-volatile, reconfigurable storage devices. This pheno…
Enhancement of the WS A Raman Mode in MoS/WS Heterostructures
Annika Bergmann-Iwe, Tomasz Woźniak, Mustafa Hemaid +9
When combined into van der Waals heterostructures, transition metal dichalcogenide monolayers enable the exploration of novel physics beyond their unique individual properties. How…
Ferroelectric Control of Interlayer Excitons in 3R-MoS / MoSe Heterostructures
Johannes Schwandt-Krause, Mohammed El Amine Miloudi, Elena Blundo +9
We investigate the interaction between interlayer excitons and ferroelectric domains in hBN-encapsulated 3R-MoS/MoSe heterostructures, combining photoluminescence experimen…
