- W2247270725 abstract "[Ca2(Co0.65Cu0.35)2O4]0.624CoO2 polycrystalline samples were prepared using sol-gel method followed by spark plasma sintering. Thermoelectric properties of the samples were examined from room temperature to 1000K. The temperature dependence of electrical conductivity shows that the hole hopping conduction mechanism is dominant for the samples. The activation energy of hopping conduction is 0.11 eV. At the temperature of about 1000K, the electrical resistivity is 7.1m cm, the thermopower is 160 μVK-1, the thermal conductivtity is 2.94Wm-1K-1 and dimensionless figure of merit reaches 0.12. These results indicate [Ca2(Co0.65Cu0.35)2O4]0.624CoO2 is a potential material for high temperature thermoelectric energy conversion." @default.
