By tailoring the neighboring-conductive-channel organic layer using a plasma-assisted-interfacial-grafting method, we introduced a molecular antenna on the surface of organic transistors to enable direct interaction between the semiconductors in the conductive channel and the target analytes in solution.

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.

AbstractOrganic thin film transistors for display applications are investigated. Different dielectric materials – inorganic and organic – have been studied with respect to their electrical performance It was found that anodic oxidation is an excellent process to achieve smooth high-k dielectrics with high breakthrough field strength. With the proposed electrolyte electrical properties were further improved. The alignment of pentacene on different insulators as well as transistors characteristics is presented.

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.

Coating Method

Thin films of poly vinyl alcohol (PVA) were prepared on pre-cleaned glass substrates by Dip Coating Method. FTIR spectrum was used to identify the functional groups present in the prepared films. The vibrational peaks observed at 1260 cm-1 and 851 cm-1 are assigned to C–C stretching and CH rocking of PVA.The characteristic band appearing at 1432 cm-1 is assigned to C–H bend of CH2 of PVA. The thickness of the prepared thin films were measured by using an electronic thickness measuring instrument (Tesatronic-TTD20) and cross checked by gravimetric method. XRD spectra indicated the amorphous nature of the films.Surface morphology of the coated films was studied by scanning electron microscope (SEM). The surface revealed no pits and pin holes on the surface. The observed surface morphology indicated that these films could be used as dielectric layer in organic thin film transistors and as drug delivery system for wound healing.
