Manifestations of the Electron-Phonon Coupling in
the Spectroscopy of High-Temperature Superconductors
Figure 6
(a) Real part of the self-energy Re from five samples both for (lower curves) and (upper curves). All Re are deduced by subtracting a bare band dispersion from the experimental one. (b) Imaginary part of the self-energy Im determined from the full width of the momentum distribution curves. (c), (d) Obtained kink energy as a function of sample numbers both for (to the left) and (to the right) from Re and Im after Iwasawa et al. [113].
