It was found that the data could be described by:

D (cm2/s) = 5.07 x 102 exp[-2.8(eV)/kT]

G.N.Wills: Solid-State Electronics, 1967, 10, 1-10

The best linear fits to the solute diffusion data ([93] to [120]) yield:

H: Ln[Do] = 0.89E – 33.6 (R2 = 0.92); Li: Ln[Do] = 1.06E – 18.8 (R2 = 0.95);

Sb: Ln[Do] = 0.30E – 14.5 (R2 = 0.63)
