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…
On Constrained Riesz Minimum Energy Problems
Dan Coroian, Peter Dragnev, Alan Legg +1
The constrained equilibrium problem for the logarithmic potential was introduced by Rakhmanov (1996) as he realized that the asymptotic distribution of the zeros of discrete orthog…
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…
Effect of spin-dependent tunneling in a MoSe/CrGeTe van der Waals heterostructure on exciton and trion emission
Annika Bergmann, Swarup Deb, Klaus Zollner +7
We study van der Waals heterostructures consisting of monolayer MoSe and few-layer CrGeTe fully encapsulated in hexagonal Boron Nitride using low-temperature photol…
Shaping Exciton Polarization Dynamics in 2D Semiconductors by Tailored Ultrafast Pulses
Omri Meron, Uri Arieli, Eyal Bahar +3
The ultrafast formation of strongly bound excitons in two-dimensional semiconductors provide a rich platform for studying fundamental physics as well as developing novel optoelectr…
