“…The optically transparent lanthanum (La)-doped lead titanate (PLT) thin films are attractive candidates for non-volatile memory [1], pyro-electric detectors [2], electro-optic modulators [3], and microwave devices [4]. Thin films offer the potential of increased speed, reduced operating voltages and enhanced efficiency, and they are especially attractive for monolithic optoelectronic integration circuits [5]. In recent years, the PLT thin films have been studied extensively [6 -8].…”

“…16,17 For rhombohedral films prepared by sol-gel method, these have been attributed the (100)-orientation of PLZT thin films on Pt substrates to the presence of a PbO buffer layer while the (111)-orientation have been mainly associated with the lattice matching between filmsubstrate or to the effect an inter-metallic phase Pt [5][6][7] Pb in the early stage of the crystallization. 18 In addition, the (111)-preferred orientations for tetragonal PLZT films prepared by rf-sputtering have been attributed to lattice mismatch with the (111)-oriented platinum substrate.…”

Polycrystalline lanthanum lead zirconate titanate (PLZT) thin films were deposited on Pt/TiO2/SiO2/Si substrates to study the effects of the thickness and grain size on their structural and piezoresponse properties at nanoscale. Thinner PLZT films show a slight (100)-orientation tendency that tends to random orientation for the thicker film, while microstrain and crystallite size increases almost linearly with increasing thickness. Piezoresponse force microscopy and autocorrelation function technique were used to demonstrate the existence of local self-polarization effect and to study the thickness dependence of correlation length. The obtained results ruled out the bulk mechanisms and suggest that Schottky barriers near the film-substrate are likely responsible for a build-in electric field in the films. Larger correlation length evidence that this build-in field increases the number of coexisting polarization directions in larger grains leading to an alignment of macrodomains in thinner films.

The light transmission through a Lead Lanthanum Zirconate Titanate (PLZT) ceramic film, having a relaxor ferroelectric composition of (9.5/65/35) was modulated at both the first and second harmonic frequencies to that of an applied field. Large changes were observed in the optical path difference within the material due to a combination of the electrostrictive and quadratic electro-optic effects. A theoretical model was developed to obtain harmonic expressions for the Fabry-Pérot transmitted irradiance, and it was successfully fitted to the experimental results.
