Abstract

Ferroelectric Bi3.15Nd0.85Ti3O12 BNdT thin films of predominant 100-010-119 orientation were grown through a cheap and simple sol–gel process both on Nb-doped 011SrTiO3 and on 011SrRuO3-011SrTiO3. Using rapid heating rates during crystallization, films containing 28% 100-010-oriented grains plus 19% 119-oriented grains were obtained on SrRuO3-SrTiO3, while 30% 100-010- and 18% 119-oriented grains were obtained on Nb:SrTiO3. The films consist of columnar grains and 90° a–b domains exist in large BNdT grains. The BNdT thin films exhibit excellent ferroelectric and dielectric properties with a remanent polarization 2Pr=39.2 μC-cm and a dielectric constant εr=184.5.
