Abstract
Perovskite PbZr052Ti048O3 PZT thin film with perfect 111orientation was achieved on CoFe2O4 seededPt111/Ti/SiO2/Si substrate by pulsed laser deposition technique using target with limited excess Pb Pyrochlore phase formation was suppressed on Pt by CoFe2O4 nanoseed layer ~7 nm and perovskite PZT was achieved at temperature as low as 550 °C CoFe2O4 seed layer that has perfect 111orientation acts as a promoter for perfectly 111orientated growth of PZT PZT film grown at 600 °C has higher degree of crystalline orientation lower surface roughness and compacted microstructure in comparison to the film grown at 550 °C The PZT film has a nanosize grainfeature structure with grain size of about 40–60 nm Perovskite formation was also confirmed by ferroelectric measurement The ferroelectric properties of PZT film grown at 600 °C is higher than that grown at 550 °C which could be attributed to the enhancement of the crystalline orientation crystallinity and microstructure of the film
