Xr. Fu et al., Preparation of highly (100)-oriented PLCT thin films on Pt/Ti/SiO2/Si substrates by a simple sol-gel process, MATER LETT, 44(2), 2000, pp. 70-74
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
