Abstract
High-performance pentacene organic thin-film transistors with double layers of the terpolymer electret poly(vinylidene fluoride/tetrafluoroethylene/hexafluoropropylene) and the polymer poly(vinyl cinnamate) as a gate dielectric are reported. The electret is a high- k dielectricpolymer with a static dielectric constant of ε = 14 . The transistors show an intrinsic field-effect mobility in the range of μ i = 1 cm 2 ∕ V s and an on- to off-current ratio of about 10 5 . High-k polymer gate dielectrics seem promising for organic nonvolatile memory and sensor field-effect transistors.Keywords
