Abstract

ABSTRACT The synthesis of lead titanate thin films by two different chemical solution deposition routes and via nanoparticle dispersions is described. The differences in decomposition kinetics of the solutions were determined and correlated to the morphology evolution and ferroelectric characteristics of the deposited films. High remanent polarisation values of up to 55 μC cm−2 were obtained by the sol-gel method as well as the nanoparticle dispersion technique. Measurements of the dielectric properties of the films revealed low leakage current densities in the range of 10−6 A cm−2 and a maximum dielectric constant of ∼360.
