Electron-Phonon Coupling Deduced from Phonon Line Shapes


We investigate the Fano-type line shape of the Ba mode of Y1−xCaxBa2Cu3O6+y films observed in Raman spectra with A1g symmetry. The line shape is described with an extended Fano formula that allows us to obtain the bare phonon parameters and the self-energy effects based on a phenomenological description of the real and imaginary part of the lowenergy… (More)
