“…Subsequently, in 1957, Ritchie reported a theoretical study of electron energy loss in thin films, describing surface-localized plasmon modes [28,29]. This prediction was experimentally proven a few years later by Powell and Swan using reflection EELS, which pioneered the experimental research on surface plasmons [30].…”

Plasmons in metallic nanomaterials exhibit very strong size and shape effects, and thus have recently gained considerable attention in nanotechnology, information technology, and life science. In this review, we overview the fundamental properties of plasmons in materials with various dimensionalities and discuss the optical functional properties of localized plasmon polaritons in nanometer-scale to atomic-scale objects. First, the pioneering works on plasmons by electron energy loss spectroscopy are briefly surveyed. Then, we discuss the effects of atomistic charge dynamics on the dispersion relation of propagating plasmon modes, such as those for planar crystal surface, atomic sheets and straight atomic wires. Finally, standing-wave plasmons, or antenna resonances of plasmon polariton, of some widely used nanometer-scale structures and atomic-scale wires (the smallest possible plasmonic building blocks) are exemplified along with their applications.

“…1,2 Following those pioneering studies, electron beams have revealed many of the properties of plasmons through energy-loss and cathodoluminescence spectroscopies, which benefit from the impressive combination of high spatial and spectral resolutions that is currently available in electron microscopes and that allows mapping plasmon modes in metallic nanoparticles and other nanostructures of practical interest. [3][4][5] However, plasmon creation rates are generally low, thus rendering multiple excitations of a single plasmon mode by a single electron extremely unlikely.…”

We show that free electrons can efficiently excite plasmons in doped graphene with probabilities of order one per electron. More precisely, we predict multiple excitations of a single confined plasmon mode in graphene nanostructures. These unprecedentedly large electron-plasmon couplings are explained using a simple scaling law and further investigated through a general quantum description of the electron-plasmon interaction. From a fundamental viewpoint, multiple plasmon excitations by a single electron provides a unique tool for exploring the bosonic quantum nature of these collective modes. Our study does not only open a viable path towards multiple excitation of a single plasmon mode by single electrons, but it also reveals graphene nanostructures as ideal systems for producing, detecting, and manipulating plasmons using electron probes.

“…These Sommerfeld-Zenneck waves (SZW) are similar to SPPs, the difference that being the condition for SZW is ε i (ω) |ε r (ω)| (where ε i and ε r are the imaginary and real parts of the dielectric function, respectively), whereas for SPPs it is ε i (ω) |ε r (ω)| [38], i.e., ε r must be of different signs for the two media for SPP, which is not the case for SZW. However, despite this, both fields existed separately for a long time with their common linkages not becoming clear until 1956 and 1957, first through the work of Pines [10] and then Ritchie [28], who defined plasmons (in general) and surface plasmons (specifically), respectively.…”

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.
