Abstract
In this paper, the contribution of leakage to the hysteresis curve in thin film ferroelectric capacitors is analysed quantitatively by apply ing a very simple circuit model and experiment. Based on our previous analysis of Current-voltage characteristics in thin film ferroelectric capacitors, the deformed hysteresis loops due to leakage are calculat ed with respect to various barriers and frequencies, and are verified with our laser ablated Pt/Pb(Zr,Ti)O-3/Pt thin film capacitors. Some i nteresting phenomena, such as gap in hysteresis curves, vertical drift of hysteresis loops, etc, are discussed.
