Fig. 4: Electronic Raman scattering and charge transport parameters from the MFL fits.

Electronic Raman scattering response (χ″e(ω)) at several temperatures in a \({{{X}}}^{\prime}{{{Y}}}^{\prime}\) and b XY. Dynamical scattering rates (Γ(ω, T)) in c \({{{X}}}^{\prime}{{{Y}}}^{\prime}\) and d XY. The corresponding dynamical mass enhancement factors (m*/mb(ω, T)) in e, f, respectively. They were obtained from the marginal Fermi-liquid (MFL) fits, as shown in Fig. 3.
