We have fabricated organic thinfilm transistors (TFT's) using the smallmolecule polycyclic aromatic hydrocarbon pentacene as the active material. Devices were fabricated on glass substrates using lowtemperature ionbeam deposited silicon dioxide as the gate dielectric, ionbeam deposited palladium for the source and drain contacts, and vacuumevaporated pentacene to form the active layer. Excellent electrical characteristics were obtained, including carrier mobility as large as 0.6 cm2/Vs, on/off current ratio as large as 108, and subthreshold slope as low as 0.7 V/dec, all record values for organic transistors fabricated on nonsinglecrystal substrates.
