Abstract :
We report a semiconducting polymer light emitting field-effect transistor (LEFET) fabricated by employing a new "angled" evaporation technique to deposit the two electrodes (Ag for hole injection and Ca for electron injection). Under ambipolar conditions, recombination of electrons and holes resulted in the observation of a narrow zone of light emission within the channel. The emission zone moved across the channel as the gate bias was swept during collection of the transfer data.
