Bosonic Spectral Function and the Electron-Phonon Interaction in HTSC Cuprates

Figure 24

The spectral functions 𝛼²𝐹(𝜔) from the tunnelling conductance of Bi₂Sr₂CaCu₂O₈ for the positive and the negative bias voltages, and the averaged one [46, 47]. The averaged one is divided into 13 components. The origin of the ordinate is 2,1,0, and −0.5 from the top down. From [46, 47, 53, 54].
