Enhanced thermopower in an intergrowth cobalt oxide Li$_{0.48}$Na$_{0.35}$CoO$_{2}$

We report the measurements of thermopower, electrical resistivity and thermal conductivity in a complex cobalt oxide Li $_{0.48}$ Na $_{0.35}$ CoO $_{2}$ , whose crystal structure can be viewed as an intergrowth of the O3 phase of Li $_{x}$ CoO $_{2}$ and the P2 phase of Na $_{y}$ CoO $_{2}$ along the c axis. The compound shows large room-temperature thermopower of $\sim$ 180 $μ$ V/K, which is substantially higher than those of Li $_{x}$ CoO $_{2}$ and Na $_{y}$ CoO $_{2}$ . The figure of merit for the polycrystalline sample increases rapidly with increasing temperature, and it achieves nearly 10 $^{- 4}$ K $^{- 1}$ at 300 K, suggesting that Li $_{x}$ Na $_{y}$ CoO $_{2}$ system is a promising candidate for thermoelectric applications.
