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".

我们评估了晶格调制对固态离子导体的电性能的影响，以清除基于晶体晶格调制的开发方法的可行性。在2轴应力条件下测量常规氧离子导体YTTRIA稳定锆石（YSZ）的电导率，这是由YSZ和底物或支撑环之间的热应力产生的。结果，通过拉伸晶格调制提高电导率，并通过压缩晶格调制降低。 它显示了晶格调制作为“开发新的固态离子导体方法”的关键技术的可能性。
