Retention of thin ferroelectric VDF-TrFE copolymer films evaluated from dielectric non-linearities

Usual retention tests are based on the application of read pulses to a ferroelectric sample while the charge response is recorded. These tests, however, do not allow the continuous recording of retention as after the application of the read pulse the ferroelectric is in a new state defined by the direction of the read pulse. We propose a novel approach… CONTINUE READING
