TL;DR: In this paper, an analysis of the observed dispersion has revealed that the T1 and T2 lifetimes for the plasmon excitation are extremely rapid (2 ps).
Abstract: Measurements of the nonlinear dispersion of χ(3) have been performed on the surface plasmon resonance of aqueous colloidal gold. An analysis of the observed dispersion has revealed that the T1 and T2 lifetimes for the plasmon excitation are extremely rapid ( 2 ps). Picosecond time‐resolved transient grating experiments on the same gold sol and organic dye solutions have confirmed that the nonradiative thermal decay of the metal particles occurs on the time scale of tens of picoseconds. The application of these methods to the study of ultrafast nonradiative relaxation mechanisms in molecular systems is discussed.

TL;DR: The first observation of coupled modes of nonradiative surface plasmons excited by photons in a free-standing thin metal film is reported.
Abstract: We report the first observation of coupled modes of nonradiative surface plasmons excited by photons in a free-standing thin metal film. Excitation of these modes was achieved by introducing shallow periodic corrugations on the surfaces of a 44-nm-thick silver film, and the plasmon resonance absorption of photons was detected by a photoacoustic method.

TL;DR: A simple explicit dispersion relation is given for the surface plasmon of a semi-infinite layered electron gas and effects of the optical phonons and magnetic field are discussed.

TL;DR: In this paper, the authors used stratified electrodes made of aluminium covered by thin layers of silver and platinum, and split the optical and the electrochemical probes and open new fields to this technique: extension to the UV range and investigation of surface properties of transition metals.

TL;DR: In this paper, the currentvoltage characteristics of Al:Si and Ag:Si point contacts in the region of energy corresponding to plasmon excitation were investigated, and the resonant structure in d2I/dV2 was shown to be close to the Al surface plasmons energy.
Abstract: The authors have investigated the current-voltage characteristics of Al:Si and Ag:Si point contacts in the region of energy corresponding to plasmon excitation. They present results showing resonant structure in d2I/dV2 close to the Al surface plasmon energy and bistable switching close to the Al and Ag surface plasmon energies.

TL;DR: In this paper, a theory for the energy loss spectra of photoelectrons emitted from atoms located outside a metal sample at a distance z 0 from the surface is presented, where the intensity of losses by surface plasmon excitations is proportional to the logarithm of the length l of the trip of the photoelectron along the surface, a length which extends from the emitting atom to the surface edge.

TL;DR: In this paper, surface plasmon mediated light emission from rough metal films can be driven in a number of different ways, and the unifying feature is that each mechanism injects hot electrons into the metal.
Abstract: Surface plasmon mediated light emission from rough metal films can be driven in a number of different ways. They all show characteristic features independent of the driving mechanism. The unifying feature is that each mechanism injects hot electrons into the metal. We describe surface plasmon mediated emission from tunnel junctions in terms of a hot-electron picture. We show how this emission can be used as a spectroscopic probe of hot electron dynamics in tunnel junctions. We then describe how we used this tool to probe hot electron processes in electron injector structures, leading to important new insights into electron heating in SiO2.
TL;DR: In this article, the dispersion and linewidth of a many-electron system were evaluated using the expression for the dynamic structure function,S pl(K,ω), corresponding to the plasmon excitations in a many electron system derived earlier.
Abstract: Plasmon dispersion in Al is estimated using the expression for the dynamic structure function,S
pl(K,ω), corresponding to the plasmon excitations in a many-electron system derived earlier. An evaluation of its plasmon linewidth is also presented. It is observed that for Al both the dispersion and linewidth agree fairly well with experiments.
