Abstract :
Reported is the deposition and characterisation of lead zirconium titanate (PbZr0.4Ti0.6O3) (PZT) and lead calcium titanate (Pb0.7Ca0.3Ti03) (PCT) deposited on a gold electrode with a gold top electrode to form a capacitor structure. Pulsed laser deposition was utilised to deposit the thin films. The thin films were characterised for their dielectric constant and loss tangent variation with temperature as well as the pyroelectric coefficient. The thin films were poled to improve the pyroelectric effect. The highest pyroelectric coefficient was found to be 280 μC/m2 K for PZT film and 400 μC/m2 K for the PCT film after poling.
