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…

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…
