Abstract
Ferroelectric thin films of Bi4Ti3O12 were fabricated on several types of substrates, including quartz, steel plates, and indium‐tin‐oxide coated glass slides, by sol‐gel technique. Crystalline, transparent, and crack‐free films of 5000 Å thickness were fabricated by spinning and post‐deposition annealing at a temperature of 550 °C. Ferroelectric properties were confirmed by P‐E hysteresis loops. The dielectric constant and optical transmission were also measured.Keywords
