Abstract
Highly (100)-oriented lanthanum- and calcium-modified PbTiO3 (PLCT68/17/15 and PLCT80/10/10) ferroelectric thin films were successfully prepared on Pt /Ti/SiO2/Si substrates by a simple sol-gel spin-on process. The effects of thin film composition, film thickness and annealing temperature on the (100 ) orientation were reported. Highly (100)-oriented PLCT80/10/10 and PLCT68/ 17/15 thin films with pure perovskite could be obtained with around 0.3 and 0.45 mu m thicknesses, respectively, when annealed at 600 degrees C for 1 h. The films' crystallization and orientation were studied using the techni ques of X-ray diffraction (XRD) and atomic force microscopy (AFM). (C) 2000 Elsevier Science B.V. All rights reserved.
