Through a Lattice Darkly: Shedding Light on Electron-Phonon Coupling in the High Tc Cuprates

Figure 11

(a) Angle integrated photoemission data from two sets of data at optimal doping ( = 0.16) and one set at a slight over-doping ( = 0.18). Data has been normalized to the area under curves for energies 0.5 and above. (b) MDCs taken near along the - nodal direction as seen from the inset. The peaks correspond to the intersection of the cut with the main Fermi surface band () as well as first-order superstructure reflections () and a second-order reflection (). Overlaid on top of the red curve is a thin grey line representing the O curve shifted to model a 0.01 change in doping for comparison. Panel (a) is from [45].
