Links between electrical and optical fatigue in Pb(Zr,Ti)O sub 3 thin films

Switchable polarization can be significantly suppressed in ferroelectric (FE) materials by electrical or optical processes. Electrical suppression can occur by subjecting the FE to repeated polarization reversals; optical suppression can occur while biasing the FE near the switching threshold and il...

Description
Summary:Switchable polarization can be significantly suppressed in ferroelectric (FE) materials by electrical or optical processes. Electrical suppression can occur by subjecting the FE to repeated polarization reversals; optical suppression can occur while biasing the FE near the switching threshold and illuminating with band gap light. A link between the two processes in PZT thin-film capacitors is demonstrated by showing a relationship between the amount of the suppressed polarization induced by the two methods.
