Field-effect transistors with thin films of perylene on Si O2 and polyimide gate insulators

Field-effect transistor (FET) devices have been fabricated with thin films of perylene on Si O2 and polyimide gate insulators, and p -channel FET properties have been found in both FET devices. The perylene FET devices with Si O2 and polyimide gate insulators exhibited field-effect mobility, μ, values of 7.0× 10-3 and 3.7× 10-4 cm2 V-1 s-1, respectively, at 300 K under vacuum of 10-6 Torr. These FET devices were found to operate under atmospheric condition after exposure to air. The μ value increased with increasing temperature from 160 to 280 K, showing a hopping carrier transport.
