Modeling of two complementary ambipolar organic thin film Transistors. Application to organic inverter

In this paper, we have study two types of thin-film organic transistors as well as the organic inverter. For manufacturing p-type and n-type organic thin film transistors (OTFT), pentacene and N,N’-ditridecylperylene-3,4,9,10-tetracarboxylic diimide (PTCDI-C13H27) were used as organic semiconductors. The organic thin film transistors showed excellent ambipolar operation. This ambipolar device is very useful in building flexible integrated circuits with easy design and low power consumption. The characterization and modeling of complementary thin film organic transistors allows us to describe one of its important applications which are the "inverter". In order to better understand the operation of inverters, an analytical model has been developed to describe the electrical behavior of both types of transistors and organic inverter. The model was carried out for transistors and organic inverters made experimentally. In this present work, we present the different electrical parameters resulting from the modeling for the two types of transistors and the organic inverter wich based on the complementary OTFTs.
