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 ร 1 ), low resistivity (r 300 K $ 42 mO cm) and relatively small thermal conductivity (k 300 K $ 2.8 W K ร 1 m ร 1 ) at room temperature.
## Abstract Undoped and yttrium doped zinc oxide thin films have been deposited on corning glass by dip coating technique. The effect of doping (0โ4 wt%) and annealing temperature (300โ500 ยฐC) on the structural, optical and electrical properties of the produced films have been investigated. All the
