Abstract

The switching process of ferroelectric P(VDF-TrFE) thin films with different thicknesses is investigated through transient switching current measurements. The profile of the transient current shows a strong size effect, i.e. whether there is a peak in the transient current depends on film thickness. The different switching current profiles are attributed to a transition of switching kinetics, characterized by a unique field dependent switching time turning to a distribution of switching times in the system. Furthermore, transient current at different temperature is evaluated. The Arrhenius dependence of peak time indicates that the switching process is thermally activated. [ABSTRACT FROM AUTHOR]

Abstract

Pb 1.1 (Zr 0.30 Ti 0.70 ) O 3 (PZT) and Pb 1.1 (Zr 0.30 Ti 0.70 ) O 3 /PbTiO 3 (PZT/PT) multi-layered thin films are grown on Pt/Ti/SiO 2 /Si substrate by sol-gel method. The kinetics of current change of pyroelectric and transient response between PZT and PZT/PT ferroelectric thin films is investigated. The shape of peak in the PZT film is sharp, but that of PZT/PT is broadened. An increase in the peak value of switching current and switching time in the PZT/PT film is observed. The change of pyroelectric and transient current between PZT/PT and PZT films is discussed in terms of internal field. [ABSTRACT FROM AUTHOR]

Abstract

We demonstrate electrical polarization reversal and fabrication of quasi-periodic optical superlattice in c-cut KTiOPO4 by applying pulsed electric field to a sample. Domain switching process was monitored by recording the transient current during switching. The spontaneous polarization was measured to be 19.0 μC cm−2. The quasi-periodic domain reversal was confirmed by selective etching method.
