Abstract
We demonstrate the use of jitter-free ultrafast rise-time electrical
pulses generated by a semiconductor photoconductive switch with
femtosecond laser illumination to study the fast polarization switching
process in fully integrated, ferroelectric PNZT thin-film capacitors. The
necessary conditions for high-speed polarization switching detection are
presented. The switching behavior for various sizes of capacitors and
various rise-times of applied voltage pulses are investigated. Circuit
influence on the activation field, α, as well as application of the
Inshibashi-Merz model, are discussed.
