Small Structures, Volume 6, Issue 5, May 2025.A novel spatial segregation strategy for silicon photoelectrodes is demonstrated, where catalyst wires surrounded by tapered microwires effectively decouple competing optical and catalytic requirements. This architectural innovation enables optimal light absorption and catalytic activity while maintaining efficient charge transport, achieving 96.5 ...

Arbitrary Wavefront Manipulation in Real Space and Momentum Space Based on Elliptical Structures
Nanophotonics, Volume 15, Issue 19, 13 October 2026.Leveraging elliptical structures—while preserving real space arbitrary wavefront manipulation—we generalize the manipulation to momentum space rather than only sustaining topological singularities. Multifunctional integrated outputs, such as beam deflection and focusing, can be flexibly achieved in the near–infrared communication band, and the ...

Wavelength‐Selective Nonlinear Wavefront Control in Resonant Thin‐Film Lithium Niobate Metasurfaces
Advanced Photonics Research, Volume 7, Issue 10, October 2026.A LN metasurface converts a Gaussian pump beam into a first‐order Hermite–Gaussian second‐harmonic beam, exploiting spectrally distinct Mie‐type resonances across two nanostructured regions. The resonance‐engineered phase difference enables wavelength‐selective wavefront shaping, active only within a specific spectral window, while leaving the ...

Metal/Si Nanowire Arrays for Hot Electron Catalysis
Small, Volume 22, Issue 55, 1 October 2026.Silicon nanowire arrays enhance plasmon‐driven catalysis by strengthening light–matter interactions on Au and Ag nanostructured coatings. Hotspot accessibility, rather than near‐field intensity alone, governs photocatalytic performance, while Ag nanoshells exhibit superior activity. The work establishes high‐surface‐area Si nanowire arrays as versatile

From Nano‐ to Picocavities: The Role of Atomistic Features
Small Structures, Volume 7, Issue 10, October 2026.Atomistic features strongly affect the plasmonic response of Ag and Au nano‐ and picocavities. By analyzing induced charge densities, electric field maps, and localization areas, the role of atomistic morphology in controlling field confinement and enhancement is revealed, establishing a direct structure–property relation between atomic‐scale features ...
