Résumé

We present a hybrid surface wave device, which combines Bloch surface wave (BSW) and plasmonic nanoantennas. BSWs offer in-plane dark-field illumination. Nanoantennas squeeze the incidence into nano-size and enable far-field readout without near-field techniques.

Théorie des bandes

redresse=1.5|vignette|Représentation schématique des bandes d'énergie d'un solide. représente le niveau de Fermi. thumb|upright=1.5|Animation sur le point de vue quantique sur les métaux et isolants liée à la théorie des bandes En physique de l'état solide, la théorie des bandes est une modélisation des valeurs d'énergie que peuvent prendre les électrons d'un solide à l'intérieur de celui-ci. De façon générale, ces électrons n'ont la possibilité de prendre que des valeurs d'énergie comprises dans certains intervalles, lesquels sont séparés par des bandes d'énergie interdites (ou bandes interdites).

Tight binding

In solid-state physics, the tight-binding model (or TB model) is an approach to the calculation of electronic band structure using an approximate set of wave functions based upon superposition of wave functions for isolated atoms located at each atomic site. The method is closely related to the LCAO method (linear combination of atomic orbitals method) used in chemistry. Tight-binding models are applied to a wide variety of solids.

Electrical resistivity and conductivity

Electrical resistivity (also called volume resistivity or specific electrical resistance) is a fundamental specific property of a material that measures its electrical resistance or how strongly it resists electric current. A low resistivity indicates a material that readily allows electric current. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is the ohm-metre (Ω⋅m).

We propose here a two-dimensional material based on a single layer of violet or Hittorf's phosphorus. Using first principles density functional theory, we find it to be energetically very stable, comparable to other previously proposed single layered phosp ...

We use first-principles calculations, at the density-functional-theory (DFT) and GW levels, to study both the electron-phonon interaction for acoustic phonons and the "synthetic" vector potential induced by a strain deformation (responsible for an effectiv ...
