Abstract

An organic thin film transistor comprising: a substrate; a source electrode and a drain electrode disposed over the substrate with a channel region therebetween; a layer of organic semiconductor disposed in the channel region; a gate electrode; and a gate dielectric disposed between the layer of organic semiconductor and the gate electrode, wherein the gate dielectric comprises a cross-linked polymer and a fluorine containing polymer.
