Abstract: | Bismuth titanate Bi4Ti3O12 thin films were prepared on LaAlO3(012) substrates by a spin coating-pyrolysis process using metal naphthenates as starting materials. The c-axis oriented Bi4Ti3O12 thin films, which contained no second phases as –2 scans, were obtained by heat-treatment in air at temperatures of 600°C and above. X-ray diffraction pole-figure analysis showed that the Bi4Ti3O12 thin film has an epitaxial relationship with the LaAlO3 substrate. |
