Organic thin-film transistors have substantial benefits over their inorganic counterparts in terms of the ease of processing, weight, and cost, but tend to have low speed because of their low carrier mobility. To date, the best performance for transistors with an organic active layer has been obtained with metallic source, drain, and gate contacts, and with an inorganic gate dielectric. Halik et al. describe progress in using organic components to form all-organic transistors yielding carrier mobilities rivaling those of the hybrid devices. Using the conducting material poly (3,4-ethylenedioxythiophene) for the electrodes and poly-4-vinylphenol as the gate dielectric, they demonstrate that transistors with pentacene or poly-3-hexylthiophene in the active layer exhibit mobilities around 0.1 centimeter squared per volt-second. — ISO
