Atomically-sharp tips in close proximity of metal surfaces create plasmonic nanocavities
supporting both radiative (bright) and non-radiative (dark) localized surface plasmon modes …

Epsilon near zero (ENZ) materials exhibit strongly confined optical modes and plasmonic
response around and beyond the ENZ wavelength (λ ENZ). In order to exploit the novel …

Inelastic quantum mechanical tunneling of electrons across plasmonic tunnel junctions can
lead to surface plasmon polariton (SPP) and photon emission. So far, the optical properties …

The spectral distribution of light emitted from a scanning tunnelling microscope junction not
only bears its intrinsic plasmonic signature but is also imprinted with the characteristics of …

We theoretically present the nanofocusing of the metal-coated fiber tip under internal
excitation of the radial vector beam within visible band based on the finite difference time …

Modeling light–matter interactions in hybrid plasmonic materials is vital to their widening
relevance from optoelectronics to photocatalysis. Here, we explore photoluminescence (PL) …

Coherence between different surface plasmon polariton (SPP) modes excited by
inelastically tunneling electrons in biased metal–insulator–metal tunnel junctions (MIM‐TJs) …

Surface enhanced Raman spectroscopy is today an established technique used for
chemical fingerprinting. Here, we showcase an engineered hierarchical substrate, in which …

The D-and G-band Raman signals from random arrays of vertically aligned, multi-walled
carbon nanotubes are significantly enhanced (up to∼ 14×) while the signal from the …

A spectrum-tunable source with ultra-small volume is highly desired by on-chip information
processing technologies. As a promising candidate, light emission from electrically driven …
