Stable and metastable ferroelectric polarization analyzed by the ramp voltage technique
(2002-12-01)
The study of the stable and the metastable ferroelectric polarization of poly(vinylidene fluoride), PVDF, was performed using two successive equal sign ramp voltages, mediated by a short-circuit period. Rates from 10 V/s ...
