Abstract

Bismuth titanate (Bi₄Ti₃O₁₂) thin films were prepared on sapphire substrates (A(1120), R(1102) and C(0001) planes) by chemical vapor deposition using di-isopropoxy-bis (di-pivaloyl-methanato) titanium (Ti(i-OC₃H₂)₂(DPM)₂ ) and tri-o-tolyl bismuth (Bi(o-Tol)₃) as precursors. Bi₄ Ti₃O₁₂ films were obtained at a deposition-temperature of 853K. Deposition rate was 0.3 μm/h/. Preferred orientations were observed: sapphire (1120)//Bi₄Ti₃O₁₂(001), sapphire(1120)//Bi₄Ti₃O₁₂(100) and sapphire (0001)// Bi₄Ti₃O₁₂(104). The ferroelectric hysteresis for CVD-BIT films was measured at 50 Hz. The remanent polarization and coercive field were 227 μC/cm² and 44kV/cm, respectively.
