Abstract
Dielectric and Ferroelectric (D-E) hysteresis loop measurements were conducted for evaporated organic thin films by utilizing a newly developed sample cell. A vinylidene fluoride-trifluoroethylene (VDF/TrFE) copolymer sample with 54 mol% VDF content clearly exhibited a ferroelectric nature when an electric field of 30 MV/m was applied during the evaporation process.
