Scatter Plot from Scientific Research

Momentum-resolved time constants q of the phonon build-up for the same four fluences, compared with phonon lifetimes {q}^{{\prime} } limited by phononphonon scattering (150 K). The error bars indicate 1 confidence intervals of the fit. For the lowest fluence, the two values at the smallest momenta are omitted owing to their large uncertainties. Inset: the rate of MSD increase {0}^{-1} showcases a proportionality with the final temperature T final , where T 0 marks the base temperature of 30 K. The error bars indicate 1 confidence intervals of the fit shown in a .
