Abstract
Tilt boundaries in LiF bicrystals have been doped with Na+ ions and the resulting enhanced ionic conductivity measured. The activation energy associated with this conductivity is found to be 0.32 eV and is a constant, independent of the grain misorientation. This activation energy is the same as for the enhanced conductivity observed in Na+‐ion doped edge dislocations in LiF. The results are interpreted in terms of a disordered boundary structure containing a high vacancy concentration.This publication has 8 references indexed in Scilit:
