Figure 2
Time-resolved GISAXS analysis of the Au sample at different time delays. Panel (a) shows the experimental GISAXS data obtained at the cold reference (unexcited state), as well as at 1, 10 and 30 ps after laser irradiation. The white dashed boxes indicate the regions taken for lineouts. Panel (b) presents the corresponding simulations of the experimental conditions, illustrating the modeled evolution of the system over time. Panel (c) displays the scattering profiles for the in-plane (Qz) direction comparing both experimental and simulated results. Panel (d) shows the scattering profiles for the out-of-plane (Qy) direction. The red line represents the model used to determine the cutoff value, while the blue vertical line indicates the position of this cutoff.
