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

Figure 25

The phonon density of states 𝐹(𝜔) (PDOS) of Bi₂Sr₂CaCu₂O₈ compared with the generalized density of states (GPDOS) [159]. Atomic vibrations: O1—O in the CuO₂ plane; O2—apical O; O3—O in the BiO plane. From [46, 47].
