Abstract
The application of strain to yttria-stabilized zirconia (YSZ), which c an be realized by sandwiching a thin YSZ film epitaxially between laye rs of a material with larger lattice constants, is proposed as a means to enhance oxygen ion mobility. The possible mechanism of such an enh ancement was coefficient of oxygen ions in the superlattice is some 1. 7 times higher than in YSZ alone due to a decreased activation barrier from the strain of the YSZ structure.
