Transport Properties in (Na,Ca)Co_2O_4 Ceramics
T. Itoh, T. Kawata, T. Kitajima +1
The resistivity and thermopower of polycrystalline (Na,Ca)Co_2O_4 were measured and analyzed. Both the quantities increase with x, suggesting that the carrier density is decreased…

Specific-heat evidence for strong electron correlations in the thermoelectric material (Na,Ca)Co_{2}O_{4}
Yoichi Ando, N. Miyamoto, Kouji Segawa +2
The specific heat of (Na,Ca)Co_{2}O_{4} is measured at low-temperatures to determine the magnitude of the electronic specific-heat coefficient γ, in an attempt to gain an insight i…
