a, High-resolution bright-field electron micrograph of the FePS3 thin film at 98 K studied in the main text. Dashed red lines trace several defects present in the film, such as wrinkles and folds. b–f, Evolution of the bend contour position along several line cuts in panel a following photoexcitation by a 515-nm, 2.4-mJ-cm−2 pulse. The corresponding Bragg order for each bend contour is labelled. Note the in-phase oscillations of the contour pair in panel c.
