- Abstract
- A polymer ferroelectric array embedded in an insulating paraelectric medium, with potential uses in nonvolatile memories, is fabricated by microim-printing poly(vinylidene fluoride) (PVDF) a patterned poly(dimethylsiloxane) with mold. The localized pressure induces a polymorphic transition into ferroelectric gamma-type PVDF, whereas the unpressed raised areas (see figure) remain of the a type (paraelectric)
