Fig. 4: Arrhenius plots of volume and twin boundary diffusion.
From: Atomic scale volume and grain boundary diffusion elucidated by in situ STEM

Quantification of diffusion coefficients in dependence of temperature for (a) volume diffusion and (b) coherent twin boundary diffusion. Error bars represent the standard error. Inset in (a) shows the distribution function of apparent speeds of atoms diffusing at 350 °C and a 2D Maxwell-Boltzmann fit to that function. Dashed lines indicate a linear fit to the high temperature regime and the low temperature deviation from that straight line. Source data are provided as a Source Data file.
