Abstract
Presents the results of a theoretical survey of defect energetics in SrCl2. The authors' calculations of anion Frenkel and anion vacancy activation energies accord well with experiment. Apparent discrepancies for the case of interstitial migration suggest that the mechanism for the migration of these defects differs from that normally operating in the fluorite-structured crystals. The authors detailed study of the monovalent doped crystals shows that the equilibrium between substitutional and interstitial modes of compensation has an important effect on the conductivity of these crystals.Keywords
