Polytype-Dependent Upconversion Photoluminescence in 3R-MoS2
Omri Meron, Idan Kizel, Dror Hershkovitz +6
Ferroelectric van der Waals materials offer switchable polarization states, yet optical readout of their stacking configurations remains challenging. Here, building on the resonant…
Single-Shot Multispectral Mid-Infrared Imaging with Incoherent Light via Adiabatic Upconversion
Daniel Beitner, Ziv Abelson, Eyal Hollander +2
Multispectral mid-infrared (2-5 ) imaging is a critical capability across science and technology, offering a window into the vibrational and thermal landscape of matter that…
Shaping Ultrafast Pulses for Enhanced Resonant Nonlinear Interactions
Omri Meron, Snir Nehemia, Uri Arieli +1
Coherent control with shaped ultrafast pulses is a powerful approach for steering nonlinear light-matter interactions. Previous studies in quantum control have shown that, beyond t…
Photoluminescence Detection of Polytype Polarization in r-MoS2 Enabled by Asymmetric Dielectric Environments
Idan Kizel, Omri Meron, Dror Hershkovitz +4
The rhombohedral (r) polytypes of transition metal dichalcogenides (TMDs) constitute a novel class of two-dimensional ferroelectric materials, where lateral shifts between parallel…
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…
