| Research Abstract |
We evaluate the influence of crystal lattice modulation to electrical properties of solid state ionic conductors to clear the feasibility of the developing method based on crystal lattice modulation. Electrical conductivity of conventional oxygen ionic conductor yttria stabilized zirconia (YSZ) is measured under 2-axis stress conditions, which produced by thermal stress between YSZ and substrates or support rings. As a result, electrical conductivity is increased by tensile lattice modulation, and decreased by compressive lattice modulation. It shows the possibility of lattice modulation as the key technology in "developing method of new solid state ionic conductors".
