“…With the wealth of exotic and exciting nanoplasmonic applications [1] that are now possible with the unparalleled level of control over nanostructure growth afforded by modern fabrication techniques it is easy to forget just how closely plasmonics is linked to traditional plasma physics, both theoretically and experimentally. Other comprehensive reviews have noted the important role played by plasma physics in the development and formulation of plasmonics [2]. However, the purpose of this article is to present a discussion of how plasmonics and plasma physics are linked, not only via their theoretical and physical origins, but also through modern nanofabrication techniques -with a particular emphasis on plasmaaided nanoscale synthesis and processing.…”

Abstract. The term 'plasmon' was first coined in 1956 to describe collective electronic oscillations in solids which were very similar to electronic oscillations/surface waves in a plasma discharge (effectively the same formulae can be used to describe the frequencies of these physical phenomena). Surface waves originating in a plasma were initially considered to be just a tool for basic research, until they were successfully used for the generation of large-area plasmas for nanoscale materials synthesis and processing. To demonstrate the synergies between 'plasmons' and 'plasmas', these large-area plasmas can be used to make plasmonic nanostructures which functionally enhance a range of emerging devices. The incorporation of plasmafabricated metal-based nanostructures into plasmonic devices is the missing link needed to bridge not only surface waves from traditional plasma physics and surface plasmons from optics, but also, more topically, macroscopic gaseous and nanoscale metal plasmas. This article first presents a brief review of surface waves and surface plasmons, then describe how these areas of research may be linked through Plasma Nanoscience showing, by closely looking at the essential physics as well as current and future applications, how everything old, is new, once again.

Nanoribbon Plasmonic Gratings and their Anomalous Interaction with Electromagnetic Waves

et al. 2012

View full text Add to dashboard Cite

One of the most promising, inexpensive methods for nanostructure fabrication is the nanosphere lithography (NSL). [ 1 -6 ] The simple concept of this technique is to self-assemble a layer (usually a monolayer) of polystyrene spheres (PS) on a fl at substrate. The layer of PS is subsequently used as a shadow mask for evaporation of thin fi lms, e.g., metallic thin fi lms. In the simplest version, NSL employs the self-assembly of a densely packed hexagonal lattice of PS and perpendicular substrate evaporation, which leads after PS removal to a honeycomb array of nano-quasi-triangles. [ 1 ] More complicated patterns and nanoparticle shapes can be obtained if the evaporation angle is statically or dynamically modifi ed. [ 7 ] Here, we demonstrate fabrication of nanoribbon gratings by employing NSL with a very shallow static evaporation. The PS diameter is reduced by ionic etching after the assembly and controls the grating geometry. We use this shallow angle NSL (SANSL) technique to make Au and Fe nanoribbon gratings deposited on transparent substrates.Interaction of gratings with the electromagnetic radiation has been studied extensively since 1902. [ 8 ] Classically, subwavelength metallic gratings are polarizers of the transmitted waves; a wave with electric fi eld polarized perpendicular to the grating lines passes through the grating with little back refl ection. In turn, a wave polarized parallel to the lines is strongly back refl ected. This follows from simple boundary conditions at the perfect metal surface: [ 9 ] the parallel to the metal surface component of the electric fi eld must vanish, but the perpendicular one does not. Thus, the wave polarized parallel to the grating lines cannot pass since it would have to have wavelength λ = 2 d / n (where d is the interline distance and n = 1,2,3..) in order to assure the vanishing fi eld nodes at the metal surfaces of the neighboring grating lines. This cannot happen, since in the subwavelength limit λ > > d . In the optical range, most metals (e.g., Au, Ag) cannot be considered as perfect and thus the above analysis is no longer valid. In this range, some metals can support various plasmonic oscillations, including the surface plasmon polariton (SPP). [ 11 ] The extraordinary optical transmission discovered by Ebbesen et al. [ 12 , 13 ] has been identifi ed as due to the periodicity enabled SPP.Here we study the optical transmission in the visible and infrared frequency ranges through the Au and Fe nanoribbon gratings made by SANSL. At low frequencies (large wavelength λ ) the gratings act as polarizers, as expected. For the non-plasmonic Fe ribbons, this behavior extends into the visible range. For the plasmonic Au ribbons, on the other hand, the tendency reverses in the visible range, with minimum transmission at λ = 600 nm for the perpendicular polarization. We show that this effect is due to excitation of a plasmonic dispersionless mode, with induced charges oscillating perpendicular to the wire axis in each wire.The fi rst step in the SANSL is the prepa...

Photothermal Membrane Distillation for Seawater Desalination

et al. 2016

Thermoplasmonic effects notably improve the efficiency of vacuum membrane distillation, an economically sustainable tool for high-quality seawater desalination. Poly(vinylidene fluoride) (PVDF) membranes filled with spherical silver nanoparticles are used, whose size is tuned for the aim. With the addition of plasmonic nanoparticles in the membrane, the transmembrane flux increases by 11 times, and, moreover, the temperature at the membrane interface is higher than bulk temperature.
