Arrhenius plots for pure multilayer MF (31–53 ML). Points show ﹩\mathrm{ln}{r}_{{\rm{des}}}﹩ (ML s⁻¹) plotted against 1/T for the objectively selected leading-edge interval. Dashed lines show the fixed-ν fits, where ν = ν_TST(T_rep) is held constant and E_des is determined from the slope. Thin solid lines show the corresponding free-intercept linear fits for comparison. The linear behavior confirms coverage-independent multilayer desorption kinetics.
