Extended Data Fig. 2: Single-shot dynamics of vortex supercrystal formation measured near the 002 Bragg peak.
From: Non-equilibrium pathways to emergent polar supertextures
The detector planar surface, intersecting the V satellite peak (marked in the inset and shown in Extended Data Fig. 1a) and VSC satellite peaks, probes a detailed temporal evolution of the nonvolatile phase transformation in a [(SrTiO3)16/(PbTiO3)16]7.5 superlattice sample. The diffraction geometry probes an extended time dependence of VSC growth, where selected time delays are marked in the inset for changes in the dynamical behavior. The logarithmic scale (false color) is kept the same in all individual detector images after photon count rate normalization to the X-ray beam intensity monitor. The vertical position in the images shows qy values relative to the image center, where the latter intersects the crystal truncation rod. The horizontal position in the images mixes the qx and qz components of the peaks. Different regimes captured during the dynamical evolution of phase transformations are marked in the inset.
