In chemical physics, atomic diffusion is a diffusion process ... coefficient, which is a combination of lattice, and grain boundary diffusion coefficients.

In this equation, the diffusion coefficient is related to the mobility by comparison with Fick's first law. The relationship is remarkable: if ∂µ. A. /∂C. A.
