An approach for measuring conductivity of thin-film electrolytes in an out-of-plane configuration, amenable to high-throughput experimentation, is presented. A comprehensive analysis of the geometric requirements for success is performed. Using samaria-doped ceria (Ce_0.8Sm_0.2O_1.9, SDC) excellent agreement between bulk samples and thin films with continuous and patterned electrodes, 100–500 μm in diameter, is demonstrated. Films were deposited on conductive Nb-doped SrTiO₃, and conductivity was measured by AC impedance spectroscopy over the temperature range from ∼200 to ∼500 °C. The patterned electrode geometry, which encompassed an array of microdot metal electrodes for making top contact, enabled measurements at hundreds of positions on the film, implying the potential for measuring hundreds of composition in a single library.

高通量实验的平面外离子电导率测量配置

提出了一种适用于高通量实验的测量面外配置的薄膜电解质电导率的方法。对成功的几何要求进行了全面的分析。使用掺杂samaria的二氧化铈（Ce _0.8 Sm _0.2 O _1.9，SDC）证明了散装样品与带有连续和图案化电极（直径为100–500μm）的薄膜之间的优异一致性。将膜沉积在掺杂Nb的导电SrTiO _3上，并通过交流阻抗谱在〜200至〜500°C的温度范围内测量电导率。图案化的电极几何结构（其中包含用于进行顶部接触的微点金属电极阵列）使得能够在膜上的数百个位置进行测量，这暗示了在单个库中测量数百种成分的潜力。
