Plasmons in graphene on uniaxial substrates
I. Arrazola, R. Hillenbrand, A. Yu. Nikitin
Placing graphene on uniaxial substrates may have interesting application potential for graphene-based photonic and optoelectronic devices. Here we analytically derive the dispersio…
Comment on "Weyl fermions and the anomalous Hall effect in metallic ferromagnets"
David Vanderbilt, Ivo Souza, F. D. M. Haldane
We point out that, contrary to an assertion by Chen, Bergman and Burkov [Phys. Rev. B 88, 125110 (2013)], the non-quantized part of the intrinsic anomalous Hall conductivity can in…
Energy bands in graphene: Comparison between the tight-binding model and {\it ab initio} calculations
E. Kogan, V. U. Nazarov, V. M. Silkin +1
We compare the classification of the electron bands in graphene, obtained by group theory algebra in the framework of tight-binding model (TBM), with that calculated in the density…
Electronic and plasmonic phenomena at graphene grain boundaries
Z. Fei, A. S. Rodin, W. Gannett +13
Graphene, a two-dimensional honeycomb lattice of carbon atoms, is of great interest in (opto)electronics and plasmonics and can be obtained by means of diverse fabrication techniqu…
Strong plasmon reflection at nanometer-size gaps in monolayer graphene on SiC
Jianing Chen, Maxim L. Nesterov, Alexey Yu. Nikitin +12
We employ tip-enhanced infrared near-field microscopy to study the plasmonic properties of epitaxial quasi-free-standing monolayer graphene on silicon carbide. The near-field image…
Controlled nucleation of topological defects in the stripe domain patterns of Lateral multilayers with Perpendicular Magnetic Anisotropy: competition between magnetostatic, exchange and misfit interactions
A. Hierro-Rodriguez, M. Velez, R. Morales +5
Magnetic lateral multilayers have been fabricated on weak perpendicular magnetic anisotropy amorphous Nd-Co films in order to perform a systematic study on the conditions for contr…
