| Abstract: | The role of lattice simulation in the development and understanding of anionic conduction in the fluorite structure oxides is reviewed in this paper. The major influence of dopant-vacancy interactions in determining the activation energy for conduction is stressed, with reference to recent calculations on the effect of cation size on defect pair binding energies. Finally the relationship between the pair bonding energy and deviations from Vegard's law in these oxides is explored. |
