Fig. 4. Diffraction patterns collected at 70 ps temporal delay from (a) a uniform sample and (b) a sample containing wrinkle defects. (c) List of the integrated intensities ratio of the 120 and 130 spots at 0 ps and 70 ps time delay from uniform sample and wrinkle sample. And the calculated intensity ratio I120/I130 based on structure factors from the Td and 1T′ phases. (d) Simulated diffraction pattern from the monoclinic 1T′ phase of WTe2 at the [001] zone axis of 1T′. (e) Simulated diffraction pattern aligned to the c direction of the Td/T* phases (i.e. reciprocal vector c* direction of 1T′).
