Permeation of D in Cr2O3

$$ P = P_0 \exp\left(-\frac{E_\mathrm{p}}{k_\mathrm{B}T}\right) $$

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

Comment

120nm composite seen to decrease permeability up to a certain Cr2O3 thickness (80nm). Self-made apparatus that had a permeation chamber and vacuum.
