a, b Fluence-dependent temporal response of the ν = −1, −2 states, respectively. The time traces were averaged in a narrow window about the maximum of the lowest energy WSe2 moiré exciton sensor. Each fluence-dependent transient has been normalized for clear comparison of the dynamical response (see Supplementary Fig. 7 for unnormalized data where the overall signal trend is preserved). Data are shown in shaded colors while the fits used for time constant extraction are shown in black. See the Methods section for further details. Throughout the panels, increasing pump fluence is shown from light to dark shades. All fluence-dependent data are colored consistently for each of the filling factors throughout the figure. All data were collected at 11 K. c, d To more easily and directly visualize the trends in the fluence-dependent dynamics (without the substantial interlayer phonon response), the normalized fits from (a, b) are shown in (c, d), respectively. Arrows indicating the time constants associated with the disordering dynamics (τd) and recovery dynamics (τr) are labeled in (d).
