Abstract

We report the effects of circuit parameters such as load resistance and capacitor size on the pulse switching current responses of ferroelectric capacitors. Fully integrated (La,Sr)CoO3/Pb(Nb,Zr,Ti)O3/(La,Sr)CoO3 thin film capacitors were used. The switching response is strongly dependent on load resistance and capacitor size. With increasing load resistance and capacitor size, switching time increased. These results were explained in terms of RC time constant of measuring circuit.
