Popis: BaTiO3 (BTO) thin film capacitors were deposited on Ni substrate using rf magnetron sputtering. Microstructural studies by x-ray diffraction and transmission electron microscopy reveal that the as-grown BTO films have the columnar structure and the good interface structure. Postdeposition anneal results in the recrystallization of BTO films. The electrical measurements exhibit that the BTO films have high capacitance densities and low leakage currents.
