Thermoelectric properties of the hole-electron coexisting-type transition-metal multiple oxides

制备了晶体结构由多个不同晶体配位多面体组成的过渡金属氧化物单晶/多晶样品，并对其职业特性进行了评价。塞贝克系数、电导率、电子态计算等特征表明，由两种或多种混合离子态引起的各位之间的电子交换反应和歧化反应，使2h -钙钛矿型钴酸钙和尖晶石型钴酸钌处于空穴和电子共存状态。

The single crystal/polycrystal sample of the transition metal oxides in which the crystal structure consisted of several crystallographically different coordination polyhedrons were produced, and the career characteristic was evaluated. Some characteristics such as the Seebeck coefficient, electrical conductivity, and electronic state calculation showed that the 2H-perovskite type calcium cobaltite and spinel-type ruthenium cobaltite were in the coexistence state of the hole and electron by the electron exchange reaction and disproportionation reaction between each site resulting from two or more mixed ionic states.
