Excitation of surface plasmons at a SiO2/Ag interface by silicon quantum dots: Experiment and theory [PDF]

open access: yes, 2006
The excitation of surface plasmons (SPs) by optically excited silicon quantum dots (QDs) located near a Ag interface is studied both experimentally and theoretically for different QD-interface separations. The Si QDs are formed in the near-surface region

On Modeling of Plasmon-Induced Enhancement of the Efficiency of Solar Cells Modified by Metallic Nano-Particles

open access: yesNanomaterials, 2018
We demonstrate that the direct application of numerical packets like Comsol to plasmonic effect in solar cells metallically modified in nano-scale may be strongly inaccurate if quantum corrections are neglected.

Polarization-controlled anisotropy in hybrid plasmonic nanoparticles

open access: yesNanophotonics, 2022
Anisotropy has played a critical role in many material systems, but its controllable creation and modulation have been a long-lasting challenge for the scientific communities. Polarization-addressed anisotropy appears more attractive among all approaches

Plasmon Geometric Phase and Plasmon Hall Shift [PDF]

open access: yesPhysical Review X, 2018
The collective plasmonic modes of a metal comprise a pattern of charge density and tightly-bound electric fields that oscillate in lock-step to yield enhanced light-matter interaction. Here we show that metals with non-zero Hall conductivity host plasmons with a fine internal structure: they are characterized by a current density configuration that ...

Acoustic plasmons in extrinsic free-standing graphene

open access: yesNew Journal of Physics, 2014
An acoustic plasmon is predicted to occur, in addition to the conventional two-dimensional (2D) plasmon, as the collective motion of a system of two types of electronic carriers coexisting in the same 2D band of extrinsic (doped or gated) graphene.

Detecting Selective Protein Binding Inside Plasmonic Nanopores: Toward a Mimic of the Nuclear Pore Complex

open access: yesFrontiers in Chemistry, 2018
Biosensors based on plasmonic nanostructures offer label-free and real-time monitoring of biomolecular interactions. However, so do many other surface sensitive techniques with equal or better resolution in terms of surface coverage.

Curved Gratings as Plasmonic Lenses for Linearly Polarised Light

open access: yes, 2015
The ability of curved gratings as sectors of concentric circular gratings to couple linearly polarized light into focused surface plasmons is investigated by theory, simulation and experiment.

Plasmonic biosensors [PDF]

open access: yesWIREs Nanomedicine and Nanobiotechnology, 2014
The unique optical properties of plasmon resonant nanostructures enable exploration of nanoscale environments using relatively simple optical characterization techniques. For this reason, the field of plasmonics continues to garner the attention of the biosensing community.

Anisotropic Acoustic Plasmons in Black Phosphorus [PDF]

open access: yes, 2017
Recently, it was demonstrated that a graphene/dielectric/metal configuration can support acoustic plasmons, which exhibit extreme plasmon confinement an order of magnitude higher than that of conventional graphene plasmons.
