R. Bourguiga et al., Simulation of I-V characteristics of organic thin film transistor: Application to the dihexylquaterthiophene, EPJ-APPL PH, 14(2), 2001, pp. 121-125
Metal-Insulator-Semiconductor Field-Effect-Transistors based on Dihexyl- qu
aterthiophene (DH4T), has been realized. Unlike conventional MISFET, these
devices work through the modulation of an accumulation layer at the semicon
ductor-insulator interface. An analytical model that describes the operatio
n of organic thin-film-transistors based on a simple trap distribution, wit
h a single shallow trap level located between the valence-band edge and the
Fermi level, has been used to determine some microscopic parameters such a
s the mobility, the density of traps and the corresponding level of traps.
