electron–phonon interaction in metalsApplications of the first-principles linear-response method for calculating electron–phonon coupling parameters are presented. Calculations show that the electron–phonon coupling in the lowtemperature 9R phase of Li is significantly weaker than in the room-temperature...
Electron-phonon interaction in the f-band metals La, Ce and Th: Electronic aspects including the spin-orbit interactions The electron-ion scattering parameter η is calculated for the f-band metals La, Ce and Th using self-consistent muffin-tin potentials. The corrections wit... WE Pickett -...
For low energies, this is a direct measurement of the energy dependence of the electron-phonon interaction strength of electrons in a specific orbit on the Fermi surface. Also for higher energies effects of the anisotropy of the electron-phonon interaction are observed....

EPW is an open-source software for ab initio calculations of electron–phonon interactions and related materials properties. The code combines density functional perturbation theory and maximally localized Wannier functions to efficiently compute electro
,Bobrov,L N.摘要: We review investigations of the electron-phonon interaction (EPI) in metal diborides MeB[SUB2] (Me = Zr, Nb, Ta, Mg) by point-contact (PC) spectroscopy. For transition metal) compounds the PC EPI functions were recovered and EPI parameter λ ≲ 0:1 were ...
Phonon-Induced Features in Optical Spectra of Quantum Dots: Breakdown of the Adiabatic Approximation. Second, it includes a multimode dielectric model of LOphonons and of the electron-phonon interaction in confined systems. Our approach is applied to ... Devreese,T J.,Fomin,... - International...
electron−phonon interactionangle‐resolved photoemissionThe electron–phonon coupling in the Rashba-split two-dimensional electron gas near the surface of the topological insulator Bi2Se3 is studied by temperature-dependent angleresolved photoemission. The coupling strength is found to be rather weak, ...
Electron–phonon coupling is often involved in localization of charge carriers in crystalline materials. For example, in the case of polaron formation, the carriers locally distort the atomic lattice and the distortions trap the carriers when the electron–phonon coupling strength is large enough5. A...
