photoferroelectric effect

photoferroelectric effect

[¦fōd·ō¦fer·ō·i′lek·trik i‚fekt]
(solid-state physics)
An effect observed in ferroelectric ceramics such as PLZT materials, in which light at or near the band-gap energy of the material has an effect on the electric field in the material created by an applied voltage, and, at a certain value of the voltage, also influences the degree of ferroelectric remanent polarization. Abbreviated PFE.
