Plasmons driven by single electrons in graphene nanoislands

Plasmons driven by single electrons in graphene nanoislands

Plasmons produce large confinement and enhancement of light that enable applications as varied as cancer therapy and catalysis. Adding to these appealing properties, graphene has emerged as a robust, electrically tunable material exhibiting plasmons …

Tuning the influence of metal nanoparticles on ZnO photoluminescence by atomic-layer-deposited dielectric spacer

There is increasing interest in tuning the optical and optoelectronic properties of semiconductor nanostructures using metal nanoparticles in their applications in light-emitting and detection devices. In this work we study the effect of a …

Blueshift of the surface plasmon resonance in silver nanoparticles studied with EELS

Blueshift of the surface plasmon resonance in silver nanoparticles studied with EELS

We study the surface plasmon (SP) resonance energy of isolated spherical Ag nanoparticles dispersed on a silicon nitride substrate in the diameter range 3.5–26 nm with monochromated electron energy-loss spectroscopy. A significant blueshift of the …

Promises and challenges of nanoplasmonic devices for refractometric biosensing

Promises and challenges of nanoplasmonic devices for refractometric biosensing

Optical biosensors based on surface plasmon resonance (SPR) in metallic thin films are currently standard tools for measuring molecular binding kinetics and affinities – an important task for biophysical studies and pharmaceutical development. …

Towards nano-scale photonics with micro-scale photons: the opportunities and challenges of mid-infrared plasmonics

Towards nano-scale photonics with micro-scale photons: the opportunities and challenges of mid-infrared plasmonics

Surface plasmon polaritons and their localized counterparts, surface plasmons, are widely used at visible and near-infrared (near-IR) frequencies to confine, enhance, and manipulate light on the subwavelength scale. At these frequencies, surface …
