La doped PZT 60/40 films by MOD technology

摘要: Abstract Ferroelectric La doped PZT 60/40 thin films with uniform composition have been synthesized using metallo-organic precursor solutions. These precursors stored for more than four years and are very stable in ambient conditions, compared to the sol-gel The structural properties of these studied X-ray diffraction atomic force microscopy. excellent ferroelectric films, such as less 10% polarization loss after 1011 cycles, low leakage current 3·06×10−12 A at 2 V, small separation peaks a voltage loop by small-signal measurement, attributed high quality metalloorganic solutions used this study, which carefully home-synthesized. oxygen vacancy was reduced optimizing annealing minimize blocking interface Pt electrodes suitable amount ions doped. We suggest that greater atten...
