Co-doping of thin Pb(Zr,Ti)O 3 (PZT) films with Bi and Fe to optimize the ferroelectric properties has recently gained attention particularly, for ferroelectric random access memory applications (FeRAM). This study was undertaken to understand how co-doping PZT with one atomic% Bi and Fe impacts the characteristics of capacitor ferroelectric and material properties. XRD patterns of PZT-BiFeO...
The fact that no observable change in molecular weight distribution had occurred in the samples stressed at 60°C and 90° C seems inconsistant with the results reported previously. While there is no way to quantitatively extrapolate the results obtained at higher temperatures by Holstrom and the others previously mentioned, one would qualitatively expect some change, especially at 90° C.
