Evidence for forward domain growth being rate-limiting step in polarization switching in < 111 >-oriented-Pb(Zr0.45Ti0.55)O-3 thin-film capacitors

Nava Setter

We studied polarization switching of 295 nm thick -oriented-Pb(Zr0.45Ti0.55)O-3 (PZT) thin-film capacitors through a polarization hysteresis loop and piezoelectric force microscopy (PFM) on top of the Pt electrode. Positive voltage pulses of 450 kV/cm ...
