Giant Electron-Phonon Anomaly in Doped and Other Cuprates

Figure 15

Qualitative picture of the difference in the linewidths of the bond-stretching phonon in optimally-doped (x = 0.15) and overdoped (x = 0.3) La2-xSrxCuO4 as a function of wavevector in the ab-basal plane based on [30, 37]. The units are meV. The solid line indicates the [100] direction along which most of measurements were performed.
