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…
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…
Excitonic signatures of ferroelectric order in parallel-stacked MoS
Swarup Deb, Johannes Krause, Paulo E. Faria Junior +6
Interfacial ferroelectricity, prevalent in various parallel-stacked layered materials, allows switching of out-of-plane ferroelectric order by in-plane sliding of adjacent layers.…
Polarization Saturation in Multi-layered Interfacial Ferroelectrics
Wei Cao, Swarup Deb, Maayan Vizner Stern +5
Van der Waals (vdW) polytypes of broken inversion and mirror symmetries were recently shown to exhibit switchable electric polarization even at the ultimate two-layer thin limit. T…
