Melilite-type [A2]2[BI]2[BII2O7]2 gallates are promising ion conducting electrolytes for deployment in solid oxide fuel cells. Single crystals of [CaLa]2[Ga]2[Ga2O7]2, grown in an optical floating zone furnace, were investigated using a combination of transmission electron microscopy and single crys...
