Abstract

Highly (100) oriented Ba_0.9Sr_0.1TiO₃/LaNiO₃ heterostructures have been grown on Si(100) using chemical solution routes. X-ray diffraction analysis shows that Ba_0.9Sr_0.1TiO₃ thin films are high (100) orientation (α₁₀₀=0.92). Atomic force microscopy investigation shows that they have large grains about 80-200 nm. A Pt/Ba_0.9Sr_0.1TiO₃/LaNiO₃ capacitor has been fabricated and showed excellent ferroelectricity, the remnant polarization and coercive field are 10.8 μC/cm² and 96 kV/cm, respectively. The electric field dependence of capacitance measurement shows that the capacitor has large capacitance tuning ([C_max-C_min]/C_max×100%) of 63%. The Ba_0.9Sr_0.1TiO₃ thin films have high dielectric constant (ε) of 200 at 1 MHz.
