Layered misfit cobaltite Bi 2 Ca 2.4 Co 2 O y has been synthesized by a sol-gel method. This compound exhibits large thermoelectric (TE) power (S 300 K $ 170 mV K Γ 1 ), low resistivity (r 300 K $ 42 mO cm) and relatively small thermal conductivity (k 300 K $ 2.8 W K Γ 1 m Γ 1 ) at room temperature.
