Chiral, Electronically Decoupled Layers of 1T'-WS2 Topological Insulator via Neutral-Molecule Intercalation
Jiaze Xie, Fatmagül Katmer, Fang Yuan +9
Monolayer 1T'-WS2 is predicted to be a two-dimensional topological insulator, but its intrinsic electronic properties are masked by strong interlayer coupling in its metallic and s…
A Sliding Ferroelectric Resonant Tunnel Junction
Noam Raab, Renu Yadav, Yakov Bloch +7
Ferroelectric tunnel junctions (FTJs) leverage polarization-dependent tunneling through ultrathin barriers to enable two-terminal, non-volatile memory and logic. Although conceptua…
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…
Switching Graphitic Polytypes in Elastically Coupled Islands
Nirmal Roy, Simon Salleh Atri, Yoav Sharaby +5
Van der Waals polytypes are commensurate configurations of two-dimensional layers with discrete crystalline symmetries and distinct stacking-dependent properties. In graphitic poly…
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…
