Research Abstract

We have studied structural and physical properties of the novel 1-dimensional cobalt-oxide system Ca1-xNaxCo2O4. It was found that the heavily Na-substituted phases with x = 0.4 - 0.6 can exhibit metallic conductivity and unusually large thermoelectric power which is comparable to that in a layered cobalt oxide Ca3Co4O9. A possible mechanism of the large thermoelectric power is discussed from the viewpoint of the band structure and the strong electronic correlation in the 3d electron system.
