Abstract Bottom‐up assembly of nanoparticle‐on‐mirror (NPoM) nanocavities enables precise inter‐metal gap control down to ≈ 0.4 nm for confining light to sub‐nanometer scales, thereby opening opportunities for developing innovative nanoph

Unlike surface plasmon resonance sensors that detect integral changes to the optical properties of a sample, surface plasmon polariton-microscopy techniques can detect isolated nanoparticles in real-time through their plasmonic image, even of sub-wav

Metallic gyroid metamaterials are formed by a combination of nanoplasmonic helices leading to unique and complex optical characteristics. To unravel this inherent complexity we set up an analytic tri-helical metamaterial model that reveals the underl

Plasmonic nanoantennas have the ability to confine and enhance incident electromagnetic fields into very sub-wavelength volumes, while at the same time efficiently radiating energy to the far-field. These properties have allowed plasmonic nanoantenna

Resistive switches, which are also known as memristors, are low-power, nanosecond-response devices that are used in a range of memory-centric technologies. Driven by an externally applied potential, the switching mechanism of valence change resistive

The properties of nanoplasmonic structures depend strongly on their geometry, creating the need for high-precision control and characterization. Here, by exploiting the low activation energy of gold atoms on nanoparticle surfaces, we show how laser i

In the strong coupling regime, photons and excitons exchange energy very rapidly such that they blend together, forming hybrid plexcitonic states. Recently, strong coupling of plasmons with a single fluorescent molecule was realized for the first tim

Plasmonic nanoantennas offer intense confinement of light, to volumes even below the diffraction limit. Routine scattering analysis offers limited information on near-field intricacies. Therefore, we adopt a quasinormal mode approach to reveal the st
