Extended Data Fig. 1: Pump-probe diffraction snapshots of WSe2/MoSe2.

(a) 2° WSe2/MoSe2 at a 1 ps pump-probe delay, showing the change in diffraction intensity. Direct image is shown inset. (b) 57° WSe2/MoSe2 at a 1 ps pump-probe delay, showing the change in diffraction intensity. Direct image is shown inset.
