“…The same type of plasmons was recently found in some other atomic-wire systems [79][80][81][82], and two-dimensional plasmon (sheet plasmon) was also reported [39][40][41][42].…”

“…Since the supporting medium of plasmon is an inherent 2D system (there is no top or bottom surface) and there is no subband in the electronic band, only one intraband 2D plasmon mode is possible in such a system. Such a plasmon is also possible in a doped graphene where the metallic band near the Dirac point is responsible for the intraband plasmonic excitations [41,42].…”

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.

“…Ultrathin graphitic films and, sometimes, even monolayers were grown on metal substrates, [49][50][51][52][53] insulating carbides, [54][55][56][57] and graphite [35] (see Figure 3 d). The first papers I am aware of go back to 1970, when Grant and Haas reported graphitic films on Ru and Rh [49] and Blakely et al on Ni.…”

“…[50] Epitaxial growth on insulating substrates was first demonstrated by van Bommel et al in 1975, [54] whereas Oshima et al found other carbides allowing graphene growth (for example, TiC). [55] The grown films were usually analyzed by surface science techniques that average over large areas and say little about the films continuity and quality. Occasionally, STM was also used for visualization and local analysis.…”

Random Walk to Graphene (Nobel Lecture)

2011

There can be only one: In their Nobel Reviews, the laureates tell the story about the ever changing, exciting scientific pathways that eventually—for example, with the aid of simple adhesive tape—led them to the discovery of graphene. Graphene is a carbon monolayer with almost magical abilities, including exceptional strength, stability, and electronic properties, with massless Dirac fermions as charge carriers.

“…We demonstrated that the thickness of graphene, and the width of graphene nano-ribbons were controlled precisely by adjusting the reaction temperature, exposure time of deposition gases and choosing the substrate [8]: Depending on the interlayer interactions between graphene and the substrate, three different configurations were known: 1) On Pt (111), the crystallographic orientations of the growing graphene does not align with those of the substrate lattices because of the weak interlayer interaction [9]. 2) On TiC (111), ZrC (111), Ni (100), Ni (755) and Pd (111), the incommensurate epitaxial sheets grew because of the strong interlayer * Corresponding author: odagen@ruri.waseda.jp interaction; there are many extra diffraction spots in the low-energy electron diffraction (LEED) patterns owing to the multiple diffraction with two different periodicity [10][11][12].…”
