ABSTRACT
An oxide thermoelectric device was fabricated using Gd-doped Ca[sub 3]Co[sub 4]O[sub 9] p-type legs and La-doped CaMnO[sub 3] n-type legs on a fin. The power factors of p legs and n legs were 4.8x10[sup -4] Wm[sup -1] K[sup -2] and 2.2x10[sup -4] Wm[sup -1] K[sup -2] at 700 °C in air, respectively. With eight p-n couples the device generated an output power of 63.5 mW under the thermal condition of hot side temperature T[sub h]=773 °C and a temperature difference ΔT=390 °C. This device proved to be operable for more than two weeks in air showing high durability. © 2001 American Institute of Physics.
