摘要

用Co、Rh混合(Co,Rh)O2层，通过固相反应成功合成了[bi2ba2o4]p(Co,Rh)O2 (BBCRO)多晶样品。x射线衍射图和电子衍射图表明，该化合物的结构与[Bi2Ba2O4]pRhO 2 (BBCO)和[Bi2Ba2O4]pCoO2 (BBRO)的结构相似。在室温下，BBCRO的热功率为102 μ v /K，电阻率为62 μ m。热电的温度依赖性与BBCO和BBRO相似。其电阻率表现为半导体性质，与BBCO和BBRO不同

Thermoelectric properties of cobalt rhodium oxides: [Bi2Ba2O4]p(Co,Rh)O2

We successfully synthesized polycrystalline samples of [Bi₂Ba₂O₄]_p(Co,Rh)O₂ (BBCRO) with Co and Rh mixed (Co,Rh)O₂ layers by solid-state reaction. The X-ray diffraction pattern and the electron diffraction patterns indicate that the structure of this compound is similar to the structure of [Bi₂Ba₂O₄]_pRhO ₂ (BBCO) and [Bi₂Ba₂O₄]_pCoO₂ (BBRO). The thermopower and the resistivity of BBCRO are 102 muV/K and 62 mOmegacm at room temperature, respectively. The temperature dependence of thermopower is similar to that of BBCO and BBRO. The resistivity, however, shows semiconducting behavior, which is different from that of BBCO and BBRO
