On‐Chip Active Supercoupled Topological Cavity

Advanced Materials, EarlyView.
The on‐chip supercoupled cavity device is demonstrated realizing a record cavity excitation distance exceeding three wavelengths, leveraging the valley‐conserved supercoupling mechanism in the valley Hall topological system. This optothermal tunable design enables new degrees of freedom for supercoupled photonic cavities in mux‐demux, lasers, sensors ...

Anomalous Phonon Softening with Inherent Strain in Wrinkled Monolayer WSe2

Advanced Materials, EarlyView.
This study introduces the first discovery of a new local strain indicator, A2′′(Γ)$A_2^{^{\prime\prime}}( \Gamma )$ mode, for monolayer WSe2‐based excitonic applications including single photon emitter by using tip‐enhanced Raman spectroscopy. The correlative investigation with density functional perturbation theory provides the origin of the anomalous
