STRUCTURAL/PROPERTY RELATIONSHIPS OF THE MIXED ELECTRONIC/IONIC CONDUCTORS BASED ON LANTHANUM GALLATE

摘要

This paper examines the physical and electrochemical properties of lanthanum gallate doped with a number of metal ion species. XRD, Raman spectroscopy and solid state NMR were used to study these systems. The effect of temperature and oxygen partial pressure was also studied on some Co-doped systems, and it was observed that the p-type conductivity increased with increasing Co-content (due to the variable valency of Co).
