title: Enhancement of the conductivity of Ba(2)In(2)O(5) through phosphate doping.
abstract: In this communication, we demonstrate the successful incorporation of phosphate into Ba(2)In(2)O(5), which leads to the conversion from an orthorhombic to a cubic unit cell. The resulting increased oxygen vacancy disorder leads to an enhancement in the oxide ion conductivity at low temperatures. In addition, in wet atmospheres, significant proton conduction is observed.
