Abstract :
Thin film transistors (TFT) comprising pentacene as the semiconductor layer and an amorphous metal oxide gate insulators with a dielectric constant around 16 were fabricated and tested. Field effect mobility values up to 0.6 cm/sup 2/ V/sup -1/ s/sup -1/ with subthreshold slopes up to 0.3 V/decade and current modulation higher than 10/sup 5/ were obtained at operating voltages ranging from 4 to 15 V. TFTs fabricated at room temperature on transparent plastic substrates and exhibiting similar transport characteristics were demonstrated.
