Abstract
The growth and characterization of (PZT) (30/70) thin films on ITO-coated glass, synthesized using a sol-gel/spin coating processing route, were investigated using x-ray diffraction (XRD), TEM, and AFM. Perovskite crystd. in a random orientation, and all unseeded films showed characteristically large (~5-10 mm diam.) rosette formations. Studies involving the use of a thin seeding layer of TiO2 on the ITO surface, have shown promising results in increasing the seeding d. of the perovskite without sacrificing the film's elec. properties. Incorporation of a TiO2 seeded PZT film into a small hybrid liq. crystal display was done, and bulk alignment of the liq. crystal adjacent to poled regions of the PZT layer was demonstrated which remained after the poling voltages were removed.
