Plasma-Material Interaction Data Set 38

Diffusivity of T in Cu

$$ D = D_0 \exp\left(-\frac{E_\mathrm{d}}{k_\mathrm{B}T}\right) $$

[In the above formula, the Boltzmann constant is expressed in \(\mathrm{eV\,K^{-1}}\).]

Comment

Value of diffusion coefficient scaled from D to T. "Reference" values given in Table 1 of Anderl et al. and calculated using the method of Baskes (1980) and the material property data from Langley et al. (p.28).
