Ferroelectric thin films based on PZT (65/35) and PZTN (65/35/4) were prepared by the chemical solution deposition using alkoxide precursors. The existence of the perovskite phase was confirmed in each film, with a strong degree of [111] orientation. After deposition of a top electrode, a sandwich structure Au/Ferroelectric/Pt has then been created in order to study the electrical properties. Ferroelectric as well as fatigue behavior has been characterized. Also, the photocurrent generated by an unpoled sample has been measured to correlate the photoresponse with previous optical results.

Abstract
Ferroelectric thin films based on PZT (65/35) and PZTN (65/35/4) were prepared by the chemical solution deposition using alkoxide precursors. The existence of the perovskite phase was confirmed in each film, with a strong degree of [111] orientation. After deposition of a top electrode, a sandwich structure Au/Ferroelectric/Pt has then been created in order to study the electrical properties. Ferroelectric as well as fatigue behavior has been characterized. Also, the photocurrent generated by an unpoled sample has been measured to correlate the photoresponse with previous optical results.File in questo prodotto:
