A relaxor ferroelectric polymer poly(vinylidene fluoride-trifluoroethylene- chlorofloroethylene) exhibits a high relative dielectric constant (k) (60). The high-k polymer is used successfully in solution processable low-voltage OTFTs as the gate insulator for the first time. Both n-channel and p-channel OTFTs based on conjugated polymers are fabricated and show carrier mobilities higher than 0.1 cm2V-1s-1at an operating voltage of 3 V.
