Show affiliationsPb(Zr0.53Ti0.47)O3 (PZT) thin films have been successfully deposited on glass, silicon and ITO coated glass substrates by a 3.3 kJ Mather type dense plasma focus device. The x-ray diffraction spectra of the films deposited on glass substrates kept at a distance of 4.2 cm from the top of the anode with 10, 15 and 25 shots show peaks at 2θ = 31.3° corresponding to the perovskite phase of PZT. Transmission electron microscopy shows the presence of 0.5 nm grains of PZT. The leakage current density is found to be 10−6 A cm−2 at a reverse voltage of 1 V, from current density–voltage (J–V) characteristics. The capacitance–voltage (C–V) characteristics show a counter-clockwise hysteresis loop with a memory window of 1.2 V. The ferroelectric characteristic has been confirmed using the polarization–field hysteresis loop. The resistance of the film is about 1 GΩ. The spontaneous polarization, remanent polarization and coercive field values are found to be 20.1 µC cm−2, 8.6 µC cm−2 and 79.9 kV cm−1, respectively.
