A universal empirical expression for the isotope surface exchange coefficients (k) of acceptor-doped perovskite and fluorite oxides

The isotope surface exchange coefficient k* determined in an 18O/16O exchange experiment characterises the exchange flux of the dynamic equilibrium between oxygen in the gas phase and oxygen in a solid oxide. At present there is no atomistic expression that relates measured exchange coefficients to...
