Abstract
- Ce-doped BaTiO[sub 3] (BTO) films were grown by pulsed laser deposition. Highly c-axis-oriented BTO:Ce/YBa[sub 2]Cu[sub 3]0[sub 7−x] bilayer structures on a SrTiO[sub 3] (100) substrate were fabricated for electrical property characterization. Typical hysteresis and butterfly type C-V plots were observed. The remanent polarization and coercive field are 3 μC/cm² and 20 kV/cm, respectively. Highly α-axis-oriented Ce-doped and undoped BTO films were also deposited on MgO(100) substrates. Their linear and quadratic electro-optic effects were measured and compared. The Ce-doped films showed a larger linear electro-optic coefficient and obvious hysteresis in the quadratic electro-optic coefficient. [ABSTRACT FROM AUTHOR]
