Single Photon Emitters in Monolayer Semiconductors Coupled to Transition Metal Dichalcogenide Nanoantennas on Silica and Gold Substrates

Advanced Optical Materials, EarlyView.
Single‐photon emitters in WSe2 are formed at strain hotspots created by transition metal dichalcogenide (WS2) nanoantennas on dielectric and metallic substrates. Enhanced emission properties and collection efficiencies are achieved experimentally, while numerical optimization predicts fluorescence enhancements of more than four orders of magnitude ...

Anisotropic Memristive Switching in NbOCl2 Enabled by Directional Oxygen Ion Migration

Advanced Science, EarlyView.
This study investigates strongly orientation‐dependent memristive switching in anisotropic NbOCl2, observed exclusively along the in‐plane c‐axis. The switching originates from direction‐selective oxygen‐ion migration and vacancy propagation that modulate the Pd/NbOCl2 Schottky barrier, enabling short‐term plasticity.
