The Debye-like relaxation mechanism in poly(vinylidene fluoride-trifluoroethylene) ferroelectric polymers

, 2009
International audienceIn this work we studied 65-nm-thick poly(vinylidene fluoride-trifluoroethylene) ferroelectric polymers films grown by Langmuir-Blodgett onto silicon substrates. Three dielectric anomalies have been unambiguously evidenced.
