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 4.8{times}10{sup {minus}4}Wm{sup {minus}1}K{sup {minus}2} and 2.2{times}10{sup {minus}4}Wm{sup {minus}1}K{sup {minus}2} at 700{degree}C in air, respectively. With eight p{endash}n couples the device generated an output power of 63.5 mW under the thermal condition of hot side temperature T{sub h}=773{degree}C and a temperature difference {Delta}T=390{degree}C. This device proved to be operable for more than two weeks in air showing high durability. {copyright} 2001 American Institute of Physics.
