Field dependence of domain-switching speeds is estimated over five orders of magnitude at temperatures of 5.4–280 K from domain-switching current transients in Pb(Zr0.4Ti0.6)O3 thin films. By using Merz's equation and nucleation-rate limited models, an ultimate domain-switching current density of 1.4 × 108 A cm−1 and nucleation time of 0.47 ps at the highest field of 0.20 MV cm−1 are extracted.
