Abstract The low mobility and large contact resistance in organic thin-film transistors (OTFTs) are the two major limiting factors development of high-performance logic circuits. Here, solution-processed OTFTs circuits reported with a polymeric gate dielectric 6,6 bis (trans-4-butylcyclohexyl)-dinaphtho[2,1-b:2,1-f]thieno[3,2-b]thiophene (4H–21DNTT) for semiconducting layer. By optimizing contr...

Crystalline thin films of organic semiconductors are a good candidate for field effect transistor (FET) materials in printed electronics. However, there are currently two main problems, which are associated with inhomogeneity and poor thermal durability of these films. Here we report that liquid crystalline materials exhibiting a highly ordered liquid crystal phase of smectic E (SmE) can solve ...

We have investigated the effects of illumination, both broadband and monochromatic, on the electrical performance of organic polymer thin-film transistors (OP-TFTs). In each case, providing the illumination is sufficiently absorbed by the organic polymer, the drain current of a device biased in the OFF-state is significantly increased. We have observed increases in the OFF-state drain current a...

There has been a remarkable progress in the development of organic electronic materials since the discovery of conducting polymers more than three decades ago. Many of these materials can be processed from solution, in the form as inks. This allows for using traditional high-volume printing techniques for manufacturing of organic electronic devices on various flexible surfaces at low cost. Many...

Organic thin film transistors have been a popular research topic in recent decades and have found applications from flexible displays to disposable sensors.

Organic Thin Film Transistors (OTFT), gated through an aqueous electrolyte, have extensively been studied as sensors in various applications. These water-gated devices are known to work both as electrochemical (Organic ElectroChemical Transistor OECT) and field-effect (Organic Field-Effect Transistor OFET) devices. To properly model and predict the response of water-gated OTFT sensors it is imp...

p-Conjugated molecular, oligomeric, and polymeric materials are of immense interest as alternatives to traditional inorganic materials for many low-cost organic-based electronics applications–including thin-film transistors (OTFTs), light-emitting diodes (OLEDs), and photovoltaic cells –owing to device processing ease, mechanical flexibility, and a large synthetic palette from which properties ...
