Fig. 2.
Temperature dependence of the CDW speckle positions within the ordered state. a A detector image of the LBCO 1/8 CDW Bragg peak at 24 K at Q = (0.236, 0, 1.5). The color-bar denotes intensity in photons s−1, and the white bar at the bottom indicates 100 detector pixels (0.0025 r.l.u). b–g The temperature dependence of speckle positions as the temperature was raised from 24 to 46 K. Zoomed-in speckle images are taken from the same detector area indicated by the red box in (a). Despite the broadening and weakening of the CDW Bragg peak, the speckles tend to persist in similar locations to 46 K, above which the speckle intensity becomes too low and noise dominates the signal
