Calcul du spectre d'excitation collective d'un superreseau a puits quantique lateral dans la limite d'effet tunnel faible et dans l'approximation de la phase aleatoire. On obtient la relation de dispersion des excitations intra et inter-sous-bandes, et on considere le couplage de mode entre elles.

Plasmons and magnetoplasmons in semiconductor heterostructures
TL;DR: In this article, the status of the theory and experiment which can contribute to our knowledge of plasmon excitations in synthetic semiconductor heterostructures is surveyed. But, beyond the presentation of the results achieved, there is a need to examine carefully the methodologies employed to obtain such results.

Confined phonon modes and hot-electron energy relaxation in semiconductor microstructures
TL;DR: In this article, the role of trapped phonon modes in determining the energy relaxation of hot electrons in low-dimensional semiconductor microstructures is discussed within a dielectric continuum model for the LO phonon confinement and a long wavelength Frohlich model for electron-phonon interaction.

Theory of plasmons in carbon nanotube bundles
TL;DR: In this paper, the authors developed a suitable theoretical framework for studying plasmons in nanotube bundles, which can also be applied to more sophisticated models for carbon nanotubes.

How One-Dimensional Are Atomic Gold Chains on a Substrate?
Simone Sanna,T. Lichtenstein,Zamin Mamiyev,Christoph Tegenkamp,Christoph Tegenkamp,Herbert Pfnür +5 more
TL;DR: One-dimensional wires are inherently unstable but can be stabilized by three-dimensional interaction with their environment, resulting in two-dimensional (2D) and 3D hybridization of 1D wires as discussed by the authors.
