Research Progress of Oxides Thermoelectric Materials

The oxides-based thermoelectric materials have been attracted widespread concerns due to their high tem- perature stability, oxidation resistance, safety and long-term durability, but their applications are limited by the ther- moelectric properties. In this paper, the research progress on several typical oxides thermoelectric materials, e.g. lay- ered cobalt oxides, perovskite-structured compounds, transparent conductive oxides and novel oxides are thoroughly discussed. In order to achieve the harmonization of thermal and electric properties in thermoelectric materials, the band structure and microstructure are depth regulated. The main issues for developing high performance thermoelec-
