摘要
Plate-like particles of (Ca0.85OH)(1.16)CoO2 were prepared in which Nd was partially substituted for Ca to improve the thermoelectric performance. The values of Seebeck coefficient of as-synthesized oxides are all positive, showing that these oxides are p-type materials. The electrical conductivity initially decreases then increases with increasing Nd-doped amount, which is the coeffect of carrier concentration and carrier mobility. The Seebeck coefficient increases with the increasing Nd-doped amount below 473K. The power factor reaches 7.06 x 10(-5) W/(m.K-2) at 573K for (Ca0.75Nd0.1OH)(1.16)CoO2.
