Abstract

We present a device model for light-emitting, ambipolar, organic field-effect transistors based on the gradual channel approximation. The model results are in very good agreement with recent experimental data. Trapping of injected carriers in localized states in the channel region is shown to be an important mechanism that can strongly affect the transfer characteristics and the light emission of these devices.
