Measurements of Raman scattering by electrons in metals: The effects of electron-phonon coupling
Year: 2012
Type: article
Abstract: We report systematic measurements of Raman scattering by electrons in elemental metals Al, Mo, Nb, Os, Pb, Re, Ta, Ti, V, W, and metallic compound LaB${}_{6}$. Experimental spectra are modeled on the base of the band structures, calculated within the density functional theory, taking properly into account the effects of electron-phonon scattering. The agreement between our measured and calculated spectra is excellent for the variety of metals, thus providing information on the electron self-energies and estimates for the electron-phonon coupling constants and temperature-dependent relaxation rates. The method can be applied to other metallic materials to evaluate an electron-phonon coupling as an alternative to transport and optical measurements.
