Parity‐Dependent THz Harmonic Generation in Electrically Pumped Micro‐Lasers Exploiting Topological Insulator–Metamaterial Gratings

open access: yesAdvanced Materials, EarlyView.
Topological insulator–metamaterials integrated with electrically driven terahertz quantum cascade lasers enable parity‐dependent harmonic generation. Bulk‐dominated Bi2Se3 favors third‐harmonic emission at 9.96 THz, whereas topological‐surface‐state‐dominated Bi2Se3, Bi2Te3, and (Bi,Sb)2Te3 generate strong second harmonics near 6.5 THz.

Adaptive Supramolecular Interactions Govern Redox‐Active Molecules in Aqueous Redox Flow Batteries

open access: yesAdvanced Materials, EarlyView.
Adaptive supramolecular interactions overcome the solubility‐stability trade‐off in aqueous redox flow batteries. Hydrophobic anions disrupt intrinsic π–π stacking to enable high solubility, while redox‐state‐dependent spin pairing and cation coordination dynamically stabilize reactive intermediates during operation.

Wafer‐Scale Direct Growth of Ultraclean Monolayer Amorphous Carbon on c‐Sapphire by Remote Catalytic Dehydrogenation

open access: yesAdvanced Materials, EarlyView.
Remote catalytic dehydrogenation enables the direct growth of monolayer amorphous carbon on a 2‐inch sapphire wafer by thermal CVD. Spatial separation of the catalyst from the growth substrate eliminates metallic residue and post‐growth processing, yielding a wafer‐scale uniform film with a random polygonal sp2‐hybridized carbon network that exhibits ...
