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 \(\mathrm{eV\,K^{-1}}\).]

120nm composite seen to decrease permeability up to a certain Cr2O3 thickness (80nm). Self-made apparatus that had a permeation chamber and vacuum. Data provided by M. Lavrentiev (UKAEA, 2024) with permission from STEP.
