Résumé
Electron–phonon coupling is discussed in the context of nanostructures and low-dimensional materials from a theoretical and modeling perspective. After a short review of historical models and modern first-principles techniques, we focus on the effects of nanostructuring and dimensionality. Various mechanisms are considered, from modifications of the joint density of states and energy selection rules, to the emergence of intrinsically different types of electron–phonon coupling in low-dimensional materials. Finally, key issues and perspectives for the future of the field are discussed.
