Metal-Insulator-Semiconductor Field-Effect-Transistors based on Dihexyl- quaterthiophene (DH4T), has been realized. Unlike conventional MISFET, these devices work through the modulation of an accumulation layer at the semiconductor-insulator interface. An analytical model that describes the operation of organic thin-film-transistors based on a simple trap distribution, with a single shallow trap level located between the valence-band edge and the Fermi level, has been used to determine some microscopic parameters such as the mobility, the density of traps and the corresponding level of traps.
