Arrhenius plot of the diffusion area covered by Ga atoms during their migration from the Ga droplets as a function of the reverse temperature. In the insets: scheme of the procedure to calculate the diffusion area (yellow zone delimitated by the dashed line) for both [1–10] (top panel) and [110] (bottom panel). Solid lines represent the inner ring and an outer ring with a marked anisotropy
