Sol-gel derived lead zirconate titanate thick films and their improved pyroelectric properties [PDF]

open access: yes, 2004
The single-layer thickness of Pb(Zr0.3Ti0.7)O3(PZT 30/70) thin films made by the sol-gel process is often restricted by the appearance of cracks when a single layer is thicker than 100 nm.

Highly efficient lead zirconate titanate ring modulator

open access: yesAPL Photonics
Advanced photonic integrated circuits require large-scale integration of high-speed electro-optic (EO) functional components on a chip. Low power consumption and high operation speed are thus key metrics for almost all integrated EO devices.
