Comparison between the reciprocal space planes a [h k 0], b [h k 0.5], c [h k 0.25], at 300 K, 205 K, 92 K, and 24 K. a The q1 modulation is visible, along with the Bragg peaks of the underlying crystal structure. The (b) plots are reported in atten0 setting, for clarity of display of the diffuse scattering in the [h k 0.5] plane. Here the q2 modulation is visible, without the Bragg peaks of the underlying crystal structure. The temperature evolution of the room temperature short-range diffuse scattering, which gradually turns in sharp Bragg satellites, is clearly visible. c The q3 modulation is visible without the Bragg peaks of the underlying crystal structure. All these cuts are obtained by keeping the hk-plane constant, while shifting the l axis in non-integer steps. The coordinates on the plots are expressed in reciprocal lattice units (r.l.u.) as (qh, qk, ql). The pixel intensity is reported in intensity units (i.u.), accounting for the number of X-ray counts per pixel. d Zoomed-in plots are also shown for selected temperatures to highlight the low-intensity peaks in the three planes.
