Ferroelectric Bi₄Ti₃O<SUB>12</SUB> films were deposited on SrTiO₃(100) and Si(100) substrate by using conductive SrRuO3 films as underlayer, and their ferroelectric and electrical properties were investigated depending on crystal structure and orientation. C-axis oriented Bi₄Ti₃O<SUB>12</SUB> films were grown on well lattice-matched pseudo-cubic SrRuO3 films deposited on SrTiO₃(100) substrate, while random-oriented polycrystalline Bi₄Ti₃O<SUB>12</SUB> films were grown on SrRuO3 films deposited on Si(100) substrate. The random-oriented polycrystalline film showed a good ferroelectric hysteresis property with remanent polarization (Pr) of 9.4 μC/㎠ and coercive field (Ec) of 84.9 ㎸/㎝, while the c-axis oriented film showed Pr=0.64 μC/㎠ and Ec=47 ㎸/㎝ in polarizaion vs electric field curve. The c-axis oriented Bi₄Ti₃O<SUB>12</SUB> film showed a dielectric constant of about 150 and lower thickness dependence in dielectric constant compared to the random-oriented film. Furthermore, the c-axis oriented Bi₄Ti₃O<SUB>12</SUB> film showed leakage current lower than that of the polycrystalline film. The difference of ferroelectric properties in two films was explained from the viewpoint of depolarization effect due to orientation of spontaneous polarization and layered crystal structure of bismuth-base ferroelectric oxide.
