Abstract :
Pentacene organic field effect transistors are fabricated using polymethyl methacrylate (PMMA) as a gate dielectric on flexible polymeric substrates like the indium tin oxide coated polyethylene terephthalate (ITO coated PET), and polyethylene napthalate (PEN) in top contact configuration. The ITO and aluminium (evaporated on PEN) act as the gate materials for the OFETs. The devices on ITO coated PET show electron mobility up to 0.07 cm2/V-s and the on/off ratios in the order of 103.
