High‐Order Nonlinear Photonic Crystal with Ordered Structures for Giant Enhancement of Frequency Tripling

Advanced Science, Volume 13, Issue 23, 23 April 2026.
A meta‐YAG crystal with artificially order/disorder structures was fabricated to realize the efficient third‐harmonic generation at 343 nm with a conversion efficiency of 4.5×10−3, surpassing six orders of magnitude compared to bulk YAG crystal. Moreover, a wide spectral tunability from 331 to 356 nm was also achieved in the meta‐YAG, indicating its ...

Scanning tunneling microscopy and spectroscopy of nanoscale twisted bilayer graphene

, 2017
Nanoscale twisted bilayer graphene (TBG) is quite instable and will change its structure to Bernal (or AB-stacking) bilayer with a much lower energy. Therefore, the lack of nanoscale TBG makes its electronic properties not accessible in experiment up to ...

Förster valley-orbit coupling and topological lattice of hybrid moiré excitons

Communications Physics
Hybrid excitons in moiré superlattices of two-dimensional (2D) semiconductors inherit the electric dipole, strong moiré trapping, and stacking optical selection rules from its interlayer part, whereas the intralayer part is intended for enhancing optical
