Left: Bulk and surface diffusion coefficients (Dv and Ds) plotted against Tg/T. The Dv values nearly form a master curve, whereas Ds values have stronger molecular dependence. A Ds upper bound from this work is shown for polyalcohols; Right: Correlation between the rates of surface crystal growth us and surface diffusion (Adapted from Chen et al. 2016)
