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.

Organic thin film transistors (OTFTs) based on dioctylbenzothienobenzothiophene (C8BTBT) and copper (Cu) electrodes were fabricated. For improving the electrical performance of the original devices, the different modifications were attempted to insert in three different positions including semiconductor/electrode interface, semiconductor bulk inside and semiconductor/insulator interface. In detail, 4,4′,4′′-tris[3-methylpheny(phenyl)amino] triphenylamine (m-MTDATA) was applied between C8BTBTand Cu electrodes as hole injection layer (HIL). Moreover, the fluorinated copper phthalo-cyanine (F16CuPc) was inserted in C8BTBT/SiO2 interface to form F16CuPc/C8BTBT heterojunction or C8BTBT bulk to form C8BTBT/F16CuPc/C8BTBT sandwich configuration. Our experiment shows that, the sandwich structured OTFTs have a significant performance enhancement when appropriate thickness modification is chosen, comparing with original C8BTBT devices. Then, even the low work function metal Cu was applied, a normal p-type operate-mode C8BTBT-OTFT with mobility as high as 2.56 cm2/Vs has been fabricated.

Organic thin film transistors (OTFTs) with silicon oxide (SiO2)/poly(4-vinylphenol) (PVP)/polymethylmethacrylate (PMMA) tri-layer structure (SPP) as dielectric layers have been fabricated. To verify the validity of such tri-layer structure, two different organic semiconductor materials such as p-type pentacene and n-type fluorinated copper phthalo–cyanine (F16CuPc) are both used for fabricating OTFTs. Comparing with the OTFTs even by using PMMA modification, the better interface quality existing between SPP dielectric and organic film leads a higher conductive efficiency for transport carriers in channel. And then the field effect carriers (hole in pentacene OTFTs and electron in F16CuPc OTFTs) mobilities are both increased obviously. Our results show the SPP dielectric structure can be widely used to improve performance of OTFTs.
