Freestanding Polymer Metasurface Supporting Higher‐Order Optical Resonances for Strong Field Enhancement in TMD Monolayers

Small, Volume 22, Issue 35, 23 June 2026.
A freestanding polymer metasurface is developed to enhance light emission from atomically thin semiconductors. By supporting higher‐order optical resonances that concentrate electromagnetic fields at the surface, the platform significantly improves coupling between light and WS2 monolayer.

Wafer‐Scale Deterministic Fabrication of Axis‐Ratio–Engineered Silicon Nanoparticles for On‐Resonance Electric–Magnetic Dipole Interference

Small, Volume 22, Issue 32, 8 June 2026.
Wafer‐scale top‐down fabrication yields silicon nanoparticles with exceptional uniformity (CV 1.7%–2.4%), enabling deterministic axis‐ratio tuning. At AR ≈$\approx$ 2.1, electric–magnetic dipoles overlap on‐resonance, producing near‐Kerker forward scattering (F/B ≈$\approx$ 12.5).

Nanophotonics for Low-Power Switches

, 2013
This chapter treats several approaches for employing nanophotonics or near-nanophotonics concepts to create low-power switches. The partly interrelated issues of low power dissipation and small device footprint are elucidated and figures of merit for ...

Protocrystalline Silicon at High Rate from Undiluted Silane

, 2004
Hot Wire Chemical Vapor Deposition (HWCVD) is shown to be a fast method for the deposition of protocrystalline silicon films from undiluted silane. Intrinsic silicon-hydrogen films (2 μm thick) have been deposited by HWCVD on plain stainless steel as ...
