Electronic temperature and two-electron processes in overbias plasmonic emission from tunnel junctions
Alberto Martín-Jiménez, Koen Lauwaet, Óscar Jover +5
The accurate determination of electronic temperatures in metallic nanostructures is essential for many technological applications, like plasmon-enhanced catalysis or lithographic n…
Symmetry of electron bands in graphene: (nearly) free electron vs. tight-binding
Eugene Kogan, Vyacheslav M. Silkin
We present the symmetry labelling of all electron bands in graphene obtained by combining numerical band calculations and analytical analysis based on group theory. The latter was…
Strong two-dimensional plasmon in Li-intercalated hexagonal boron-nitride film with low damping
Ivor Lončarić, Zoran Rukelj, Vyacheslav M. Silkin +1
The field of plasmonics seeks to find materials with an intensive plasmon (large plasmon pole weight) with low Landau, phonon and other losses (small decay width). In this paper we…
Electron energy-loss spectroscopy of quasi-two-dimensional crystals: Beyond the energy-loss functions formalism
Vladimir U. Nazarov, Vyacheslav M. Silkin, Eugene E. Krasovskii
A consistent theory of electron energy-loss spectroscopy (EELS) includes two indispensable elements: (i) electronic response of the target system and (ii) quantum kinematics of pro…
Controlling surface charge and spin density oscillations by Dirac plasmon interaction in thin topological insulators
M. Ameen Poyli, M. Hrtoň, I. A. Nechaev +5
We study the selective excitation at infrared and THz frequencies of optical and acoustic plasmonic modes supported by thin topological insulators. These modes are characterized by…
Combined effect of doping and temperature on the anisotropy of low-energy plasmons in monolayer graphene
Godfrey Gumbs, Antonios Balassis, V. M. Silkin
We compare the two-dimensional (2D) plasmon dispersion relations for monolayer graphene when the sample is doped with carriers in the conduction band and the temperature is zer…
