Ultralow‐Backscattering Induced Mode Splitting in Chipscale Valley Photonic Topological Cavities
The proposed in‐situ metrology based on mode splitting quantifies the ultralow backscattering of topological valley edge states at a single sharp corner, demonstrating near‐lossless topological transport (0.09 dB/corner) on a silicon chip. This work provides insight into the robustness of the photonic valley system and shows the great potential of ...

Controlling Collective Quasiparticle Dynamics Beyond Decoherence in Topological Interfaces
Gold nanoparticles placed above a deformed honeycomb plasmonic crystal couple to a chiral topological interface mode. The pseudospin‐split bands ψ+/ ψ− encode spin‐momentum locking, so emitters radiate directionally along the domain wall and share a common phase.

A one‐step oblique angle reactive sputtering approach enables simultaneous tuning of bulk and interfacial stoichiometry in a metal oxide/ silicon heterojunction. In case of vanadium oxides, growth angle variation controls the formation of stoichiometric SiO2, ternary SiOx(V) interlayer, and phase purity of vanadium oxide, considerably simplifying the ...

Nanoscale Ripples at the Surface of SrTiO3 Irradiated by a Broad Low‐Energy Ar+ (7 keV) Ion Beam
Broad Ar ion beam irradiation creates self‐organized ripple nanostructures on oxide surfaces. A schematic illustrates the process, while cross‐sectional STEM imaging captures the ripple morphology. Complementary elemental mapping by EELS highlights nanoscale chemical variations, linking ion‐beam nanostructuring with structural and compositional ...

Scalable Room‐Temperature Terahertz Graphene Cameras
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...
