We study the characteristics of surface plasmons propagating along graphene sheets, focusing on the effect of spatial dispersion and applied magnetostatic bias, and taking into account the influence of the surrounding media, applied electrostatic biasing f ...
We demonstrate effective surface plasmon propagation along thin gold film in a blue spectral range: the measured 0.6 degrees angular width of the plasmon excitation peak corresponds to the propagation length around 7 mu m. For this end, we prepared a speci ...
We have investigated the near-field coupling of surface plasmons to a titanium/CdS nanowire interface for two different device configurations. A bare aluminum grating on an underlying aluminum layer exhibited the expected stronger electrical signal for per ...
Localized surface plasmon absorption features arise at high doping levels in semiconductor nanocrystals, appearing in the near-IR range. The surface plasmons of Sn-doped In oxide nanocrystal films can be dynamically and reversibly tuned by postsynthetic el ...
With the development of nanotechnology, many new optical phenomena in nanoscale have been demonstrated. Through the coupling of optical waves and collective oscillations of free electrons in metallic nanostructures, surface plasmon polaritons can be excite ...
The study of the optoelectronic effects of plasmonic metal nanoparticles on semiconductors has led to compelling evidence for plasmon-enhanced water splitting. We review the relevant physics, device geometries, and research progress in this area. We focus ...
Semiconductor nanowires (NWs) possess a fascinating ability to efficiently collect and trap light into a sub-wavelength volume due to the occurrence of leaky mode resonances. The same confinement ability is manifested by metal nanostructures thanks to the ...

We show that surface plasmon polaritons (SPPs) can be concentrated to subwavelength dimensions in a nanoscale dielectric wedge on a metal substrate. An adiabatic model explains how SPPs propagating on a Ag substrate covered with a thin Si film of slowly in ...
Coupled plasmonic resonators have become the subject of significant research interest in recent years as they provide a route to dramatically enhanced light-matter interactions. Often, the design of these coupled mode systems draws intuition and inspiratio ...
The paper reports on the deposition of thin antimony (Sb)-doped SnO2 films onto gold and silver substrates using magnetron sputtering. The influence of the SnO2:Sb film on the electrochemical and surface plasmon resonance properties is investigated. The be ...
