(a) Schematic of the WTe2 structure showing the crystal's planar view, the side view where planes stack along c and the mounting geometry with respect to the X-ray beam for a tilted sample. We present the single-crystal diffraction data for a sample where b is parallel to the X-ray beam, to showcase the transition during laser on/off in (b) the 2D diffraction data and (c) the 1D diffraction data. Here the diffraction patterns are plotted in a waterfall format to reveal subtle changes in the peak profile as the laser is turned on/off and the temperature increases towards the transition point. Scans with the laser on are highlighted in red, while those with the laser off are highlighted in blue. The time step per scan is 5.2 s.
