On Proton Conductivity in Porous and Dense Yttria Stabilized Zirconia at Low Temperature


The electrical conductivity of dense and nanoporous zirconia-based thin fi lms is compared to results obtained on bulk yttria stabilized zirconia (YSZ) ceramics. Different thin fi lm preparation methods are used in order to vary grain size, grain shape, and porosity of the thin fi lms. In porous fi lms, a rather high conductivity is found at room… (More)
