Figure 2: Out-of-plane component of the electronic supermodulation.

(a) Scattered intensity line cuts along L measured on sample #1 at 50 K and 930.6 eV at fixed H=−0.245 and K=0. Average intensity in the peak region and background region of the CCD image are shown in red and grey curves, respectively. (b) Diffracted intensity for the same line cut, which is the difference between red and grey curves in a. The diffracted intensity in b shares the same scale with the intensity in a. (c) Calculated diffraction structure factor for one representative type of charge density modulation along the c axis. r.l.u., reciprocal lattice units.
