Paper Abstract

BaTiO3 thin films are commonly used as a pyroelecrtic sensor because this material has a good dielectric, ferroelectric and piezoelectric properties. This paper reports the pyroelectric sensor performance of BaTiO3/SiO2 nanocomposite thin films. The BaTiO3 nanoparticles were synthesized and deposited as nanocomposite thin films on Si/SiO2 substrates using spin coating technique. The deposited films were dried at 200 °C for 2 hours and annealed at 700 °C for 1 hour in air. Pyroelectric performance of the fabricated sensors was carried out at temperature in the range of 30 to 58 °C using short-circuit current method. The heating rate was set up to 0.4 °C/s. It was found the devices showed the pyroelectric response when heated and the pyroelectric coefficients of the devices are in the range of 43-1300 μC cm-2 K-1.
