Polyvinylpyrrolidone  /  Nickel  oxide  (PVP/NiO)  dielectrics  were fabricated  with  sol-gel  method  using  0.2  g  of  PVP  at  different working  temperatures  of  80,  150  and  200  ºC.  Structural  properties and surface morphology of the hybrid films were investigated by X- Ray  diffraction  (XRD)  and  Scanning  Electron Microscope  (SEM) respectively. Energy dispersive X-ray spec...

A new diketopyrrolopyrrole derivative 1 exhibits excellent hole mobilities of 0.7 cm(2) V(-1) s(-1) and a current on/off ratio of 10(6) under ambient conditions in bottom-gate, top-contact organic thin film transistors (OTFTs) fabricated by vacuum deposition.

TIPS-Pentacene, an organic semiconductor characterized by its good electronic properties, solubility, and stability, is used primarily in organic thin-film transistors (OTFT). This research seeks to create an OTFT by crafting a stencil, depositing the source and drain onto a substrate’s surface, and processing TIPS-Pentacene onto the channel between them. In addition, if time permits, the elect...

The effects of gate dielectrics material in organic thin film transistors (OTFTs) were investigated. The gate dielectrics were deposited by plasma enhanced chemical vapor deposition (PECVD) with cyclohexane and tetraethylorthosilane (TEOS) respectively used as organic and inorganic precursors. The gate dielectrics (gate insulators) were deposited as either organic plasma-polymer or organic–inor...

We fabricated triisopropylsilyl (TIPS) pentacene organic thin-film transistors (OTFTs) by inkjet printing method and investigated their electrical properties. The film morphology of TIPS pentacene layer and the field-effect mobility of OTFTs were greatly affected by choice of the solvent which TIPS pentacene was dissolved in. Especially the boiling point of a solvent was a critical factor that ...

Flexible organic thin-film transistors (OTFTs) have received extensive attention due to their outstanding advantages such as light weight, low cost, flexibility, large-area fabrication, and compatibility with solution-processed techniques. However, compared with a rigid substrate, it still remains a challenge to obtain good device performance by directly depositing solution-processed organic se...

Low operation voltage organic thin film transistors (OTFTs) were successfully fabricated with top contact structure at low fabrication temperature. The thin gate dielectric of OTFTs were deposited by atmospheric pressure plasma jet at the substrate temperature about 150 °C and under atmospheric pressure. The environment of processes would significantly improve the abilities of large area applic...

The waste from semiconductor manufacturing processes causes serious pollution to the environment. In this work, a non-toxic material was developed under room temperature conditions for the fabrication of green electronics. Flexible organic thin-film transistors (OTFTs) on plastic substrates are increasingly in demand due to their high visible transmission and small size for use as displays and ...

The development of new organic semiconductors with improved performance in organic thin film transistors (OTFTs) is a major challenge for materials chemists. There is a particular need to develop air-stable n-channel (electron-conducting) organic semiconductors with performance comparable to that of p-channel (hole-conducting) materials, for organic electronics to realize the benefits of comple...
