Abstract:

Experimental data on d.c. leakage currents in lead zirconate titanate thin films 210 nm are presented. The data show a flat, ohmic response up to a threshold of approximately 2.0 V, above which they satisfy a modified Childs Law, with a perfectly quadratic dependence I aV2. This suggests that at 5 V operation the film behaves as a fully depleted device. The difficulty in distinguishing between Frenkel-Poole, Schottky emission and true space-charge limited currents is briefly discussed.
