摘要
This work presents the impact of lanthanum doping on PZT leakage current behavior by comparing the amplitude of the maximum Schottky barrier lowering between PZT and lanthanum doped PZT(PLZT). PZT and PLZT films have been also estimated in terms of capacitors reliability. The time to breakdown distribution obtained with PLZT capacitors drifts by a factor 2.5, which tends to demonstrate also the benefits of lanthanum doping on improving reliability.
