  • Abstract
    The microstructure, leakage current density-electric field characteristics and fatigue characteristics for epitaxial c-axis oriented (Pb0.925La0.075)(Zr0.4Ti0.6 )O3, (PLZT) ferroelectric capacitors with layered Pt/SrRuO3 (SRO) top electrodes were investigated on PLZT films with thickness ranging from 100 to 400 nm. The leakage current for Pt/SRO/PLZT/Pt capacitors exhibited a tendency to increase with decreasing film thickness. The values of switchable polarization after 1010 cycles for Pt/PLZT/Pt capacitors as reference samples decreased up to around 17% of respective initial values, whereas the switchable polarization for Pt/SRO/PLZT/Pt capacitors showed no fatigue degradation due to polarization reversal until 1010 cycles
