This paper reports on the processing and the characterization of pentacene organic field effect transistors (OFETs) with a two-layer gate dielectric consisting of a polymer (PMMA) on a high-k oxide (Ta 2 O 5 ). This dielectric stack has been designed in view to combine low voltage operating devices,

Low-voltage pentacene organic field-effect transistors (OFETs) with different gate dielectric interfaces are studied and their performance in terms of electrical properties and operational stability is compared. Overall high electrical performance is demonstrated at low voltage by using a 100 nm-thi
## Abstract Organic field effect transistors with the organic semiconductor pentacene, using silicon substrates, were successfully built on conventional inorganic dielectrics like silicon dioxide or silicon nitride. They can drive drain currents up to 15 mA. Beyond that, polymer films were investig
