Thermal conductivity of the A_xBO_2 type layered oxides Na_0.77MnO_2 and LiCoO_2
K. Takahata, I. Terasaki
We prepared polycrystalline samples of the A_xBO_2 type layered oxides Na_0.77MnO_2 and LiCoO_2, and measured thermal conductivity from 15 to 280 K. Na0.77MnO_2 shows a low thermal…

Low thermal conductivity of the layered oxide (Na,Ca)Co_2O_4: Another example of a phonon glass and an electron crystal
K. Takahata, Y. Iguchi, D. Tanaka +2
The thermal conductivity of polycrystalline samples of (Na,Ca)Co_2O_4 is found to be unusually low, 20 mW/cmK at 280 K. On the assumption of the Wiedemann-Franz law, the lattice th…

Na-site substitution effects of the thermoelectric properties of NaCo_2O_4
T. Kawata, Y. Iguchi, T. Itoh +2
The resistivity and thermopower of NaCoO and NaCaCoO are measured and analyzed. In NaCoO, whereas the resistivity increases wi…
