Description
  • The change of the Seebeck coefficient S is exemplified in the LaCoO3 perovskites: a small hole doping result in a large positive Seebeck coefficient, while electron doping give a negative Seebeck coefficient at room temperature. At high temperature, the Seebeck coefficients of LaCoO3 and related compounds decrease to small values close to 20 μ V/K at 800 K due to the spin state transition. On the other hand, in the case of metallic-like samples as electron-doped manganites, the properties can be described up to high T in terms of a band metal. Due to the linear variation of S as a function of T and the almost constant value of rρ, the ratio S2/rρ which is crucial for high temperature applications, increases (cs)
