Low-thermal-conductivity oxide thermoelectrics based on coherently intergrown cobaltates

We showed that the sheets of octahedrally coordinated Co ions, which are the common structural element of NaxCoO2 and Ca3Co4O9 phases allow spontaneous intergrowth of the two structures leading to significant improvement of environmental stability. Furthermore coherent intergrowth of the two structural types results in effective texturing in polycrystalline material with the preferred grain growth aligned in-plane with common CoO6 layers thus allowing high electrical conductivity.
