Gap and channelled plasmons in tapered grooves: a review [PDF]
, 2015 Tapered metallic grooves have been shown to support plasmons -- electromagnetically coupled oscillations of free electrons at metal-dielectric interfaces -- across a variety of configurations and V-like profiles.

Semiconductor Quantum Plasmonics [PDF]
Physical Review Letters, 2019 We investigate the frontier between classical and quantum plasmonics in highly doped semiconductor layers. The choice of a semiconductor platform instead of metals for our study permits an accurate description of the quantum nature of the electrons constituting the plasmonic response, which is a crucial requirement for quantum plasmonics.

Advanced Functional Materials, EarlyView.The SERS spectra of reporter molecules adsorbed on chiral gold nanorods depends on the handedness of circularly polarized light (CPL‐SERS). The bisignate plasmonic CD spectra of chiral nanorods provides wavelength‐dependent CPL‐SERS. Selective discrimination of chiral nanorod handedness and different Raman reporters allow highly sensitive codification ...

Unidirectional frequency conversion of surface plasmon polaritons on metal nanowires
Micro and Nano Engineering, 2023 Hybrid nanoplasmonics is one of the most promising branch of nanophotonics which aims, in particular, to control the energy transfer between donor and acceptor nano-emitters via surface plasmons.

Double Helical Plasmonic Antennas
Advanced Functional Materials, EarlyView.Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Graphene plasmonics: physics and potential applications
Nanophotonics, 2016 Plasmon in graphene possesses many unique properties. It originates from the collective motion of massless Dirac fermions, and the carrier density dependence is distinctively different from conventional plasmons.

Tunable nonlinear graphene metasurfaces
, 2015 We introduce the concept of nonlinear graphene metasurfaces employing the controllable interaction between a graphene layer and a planar metamaterial. Such hybrid metasurfaces support two types of subradiant resonant modes, asymmetric modes of structured

Advanced Functional Materials, EarlyView.This work presents self‐propelled CRISPR/Cas9‐functionalized Au–MRs for rapid, amplification‐free, “on‐the‐fly” DNA detection. By harnessing motion‐assisted signal recovery, the platform achieved the limit of detection in low fM DNA concentrations, enabling detection across a wide dynamic range within only 5 min, which is significantly faster than any ...
