Dynamically Modulating the Surface Plasmon Resonance of Doped Semiconductor Nanocrystals

Raffaella Buonsanti, Anna Llordes Gil

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 ...

Solving surface plasmon resonances and near field in metallic nanostructures: Green's matrix method and its applications

Olivier Martin

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 ...

An RCWA Analysis of Solar Cell Back Reflectors: Comparison between Modelling and Experiment

Christophe Ballif, Hans Peter Herzig, Franz-Josef Haug, Toralf Scharf, Karin Söderström, Vincent Paeder, Ali Naqavi

We present a comparison between spectrally-resolved reflection measurements of gratings and theoretical predictions from RCWA approach. Diffraction intensities vary significantly with polarization, and surface plasmon absorption is observed around the onse ...

Plasmonic Nanofocusing in a Dielectric Wedge

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 ...

Surface plasmon coupling to nanoscale Schottky-type electrical detectors

Klaus Kern, Marko Burghard, Thomas Dufaux

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 ...

2010

An optical technique devised for the detection of the ultrasharp angular resonance of long-range surface plasmons (LRSPs) is described. The LRSPs propagate along an 8 nm-thick palladium (Pd) film deposited on a one- dimensional photonic crystal structure a ...

Chemical separations by bubble-assisted interphase mass-transfer

Demetri Psaltis, James Adleman

We show that when a small amount of heat is added close to a liquid-vapor interface of a captive gas bubble in a microchannel, interphase mass-transfer through the bubble can occur in a controlled manner with only a slight change in the temperature of the ...

2008

In this paper, we study the multiple scattering by electrically small (the radius of the cylinder is much smaller than the wavelength) plasmonic nanocylinders near surface plasmon resonance. The cylinders are assumed to be identical in dimension and compos ...

Instability of Ag nanoparticles in SiO2 at ambient conditions

Giulia Di Domenicantonio, Olivier Eugster

The room temperature stability of nanometer-sized silver clusters in silica matrices has been investigated by following the temporal evolution of their surface plasmon absorption. Ag clusters in SiO2 were prepared by either annealing silica samples doped w ...

Optical interactions in a plasmonic particle coupled to a metallic film

Olivier Martin

The interplay between localized surface plasmon (LSP) and surface plasmon-polariton (SPP) is studied in detail in a system composed of a three-dimensional gold particle located at a short distance from a gold thin film. Important frequency shifts of the LS ...
