Piezoresponse force microscopy study on ferroelectric polarization of ferroelectric polymer thin films with various structural configurations

AIP Advances, 2015
Ferroelectric polymer-based memory devices have attracted much attention due to their potential in low-cost flexible memories. However, bad retention property of recorded logic states limited their applications. Though mechanisms of retention degradation

Morphology and Ferroelectric Properties of Semiconducting/Ferroelectric Polymer Bilayers [PDF]

Macromolecules, 2019
Bilayers of the ferroelectric polymer poly(vinylidene fluoride-trifluoroethylene), P(VDF-TrFE) on semiconducting poly(3-hexyl thiophene) substrates have been prepared by sequential spin-coating. Here, we present a study of the polarization of this ferroelectric/semiconducting bilayer as a function of the semiconductor thickness by piezoresponse force ...
