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 (011)SrTiO3 and on (011)SrRuO3/(011)SrTiO3. 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/cm2 and a dielectric constant er=184.5.
