Spacer‐Less Substrate‐Integrated Metasurface for Near‐Unity Terahertz Absorption
Advanced Optical Materials, EarlyView.ABSTRACT Although conventional metal‐insulator‐metal (MIM) terahertz (THz) absorbers can provide near‐unity absorption, their multilayer stacks inevitably introduce additional thickness, mass, and residual stress, which limit their compatibility with THz thermal sensing platforms.

Color Center Formation in Silicon‐On‐Insulator for On‐Chip Photonic Integration
Advanced Optical Materials, EarlyView.ABSTRACT Color centers in silicon have great potential as single photon sources for quantum technologies. Some of them – like the T center – also possess optically‐active spins that enable spin‐photon interfaces for generating entangled photons and multi‐spin registers. This paper explores the generation of several types of color centers in silicon for

Advanced Science, EarlyView.In this work, ultrafast laser‐induced spin transfer and spin relaxation dynamics in 2D van der Waals antiferromagnetic CrI3/CrGeTe3 heterostructures are investigated. Laser excitation is demonstrated to induce pronounced interlayer nonequilibrium spin dynamics and ultrafast magnetic moment reconstruction, driving a transition from an antiferromagnetic (

Isosteric Substitution Enables Rational Design of Two‐Dimensional Energetic Crystals
Advanced Science, EarlyView.Isosteric substitution transforms a classical nitro–amine motif into two‐dimensional aminofurazans with performance beyond TATB. ABSTRACT Two‐dimensional (2D) energetic crystals dissipate mechanical insult via interlayer slip, yet their molecular design space remains narrow.

Two‐Dimensional Triferroics: From Fundamental Couplings to Multifunctional Applications
Advanced Science, EarlyView.This graphic summarizes the three main types of currently reported 2D triferroic couplings. From the structural perspective, existing systems can be broadly classified into two categories, which exhibit distinct symmetry features and coupling behaviors. Beyond the lattice difference, a third type involves the interplay among ferroelectricity, magnetism,
