Book Synopsis Organic Thin Film Transistor Integration by : Flora Li
Download or read book Organic Thin Film Transistor Integration written by Flora Li and published by John Wiley & Sons. This book was released on 2011-03-21 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on organic electronics (or plastic electronics) is driven by the need to create systems that are lightweight, unbreakable, and mechanically flexible. With the remarkable improvement in the performance of organic semiconductor materials during the past few decades, organic electronics appeal to innovative, practical, and broad-impact applications requiring large-area coverage, mechanical flexibility, low-temperature processing, and low cost. Thus, organic electronics appeal to a broad range of electronic devices and products including transistors, diodes, sensors, solar cells, lighting, displays, and electronic identification and tracking devices A number of commercial opportunities have been identified for organic thin film transistors (OTFTs), ranging from flexible displays, electronic paper, radio-frequency identification (RFID) tags, smart cards, to low-cost disposable electronic products, and more are continually being invented as the technology matures. The potential applications for "plastic electronics" are huge but several technological hurdles must be overcome. In many of these applications, transistor serves as a fundamental building block to implement the necessary electronic functionality. Hence, research in organic thin film transistors (OTFTs) or organic field effect transistors (OFETs) is eminently pertinent to the development and realization of organic electronics. This book presents a comprehensive investigation of the production and application of a variety of polymer based transistor devices and circuits. It begins with a detailed overview of Organic Thin Film Transistors (OTFTs) and discusses the various possible fabrication methods reported so far. This is followed by two major sections on the choice, optimization and implementation of the gate dielectric material to be used. Details of the effects of processing on the efficiency of the contacts are then provided. The book concludes with a chapter on the integration of such devices to produce a variety of OTFT based circuits and systems. The key objective is to examine strategies to exploit existing materials and techniques to advance OTFT technology in device performance, device manufacture, and device integration. Finally, the collective knowledge from these investigations facilitates the integration of OTFTs into organic circuits, which is expected to contribute to the development of new generation of all-organic displays for communication devices and other pertinent applications. Overall, a major outcome of this work is that it provides an economical means for organic transistor and circuit integration, by enabling the use of a well-established PECVD infrastructure, while not compromising the performance of electronics. The techniques established here are not limited to use in OTFTs only; the organic semiconductor and SiNx combination can be used in other device structures (e.g., sensors, diodes, photovoltaics). Furthermore, the approach and strategy used for interface optimization can be extended to the development of other materials systems.

In particular, the DFG with PFBT exhibits excellent memory performances, including the large memory window of 51 V, and the stable retention property more than 108 s. Third, we fabricated all organics based OFET and NFGM on kapton flexible substrates with simple fabrication process under low temperature. The large memory window of 23 V was obtained, and the multi-level data storage performance was observed for our flexible NFGM devices. In addition, the bending stability/mechanical stability test present high current on /off ratio ˃105, retention time ˃104, as well as cycling exceed 500 cycles. Based on the experiments results of this work, we highlight the efficient ways to optimize the OFET and fabricate the high performances of flexible NFGM by simple fabrication process.

Available in PDF, EPUB and Kindle. Book excerpt: This work takes advantage of high-resolution silicon stencil masks to build air-stable complementary OTFTs using a low-temperature fabrication process. Plastic electronics based on organic thin-film transistors (OTFTs) pave the way for cheap, flexible and large-area products. Over the past few years, OTFTs have undergone remarkable advances in terms of reliability, performance and scale of integration. Many factors contribute to the allure of this technology; the masks exhibit excellent stiffness and stability, thus allowing OTFTs with submicrometer channel lengths and superb device uniformity to be patterned. Furthermore, the OTFTs employ an ultra-thin gate dielectric that provides a sufficiently high capacitance to enable the transistors to operate at voltages as low as 3 V. The critical challenges in this development are the subtle mechanisms that govern the properties of aggressively scaled OTFTs. These mechanisms, dictated by device physics, are well described and implemented into circuit-design tools to ensure adequate simulation accuracy.

Book Synopsis Practical Guide to Organic Field Effect Transistor Circuit Design by : Antony Sou
Download or read book Practical Guide to Organic Field Effect Transistor Circuit Design written by Antony Sou and published by Smithers Rapra. This book was released on 2016-04-21 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of organic electronics spans a very wide range of disciplines from physics and chemistry to hardware and software engineering. This makes the field of organic circuit design a daunting prospect full of intimidating complexities, yet to be exploited to its true potential. Small focussed research groups also find it difficult to move beyond their usual boundaries and create systems-on-foil that are comparable with the established silicon world.This book has been written to address these issues, intended for two main audiences; firstly, physics or materials researchers who have thus far designed circuits using only basic drawing software; and secondly, experienced silicon CMOS VLSI design engineers who are already knowledgeable in the design of full custom transistor level circuits but are not familiar with organic devices or thin film transistor (TFT) devices.In guiding the reader through the disparate and broad subject matters, a concise text has been written covering the physics and chemistry of the materials, the derivation of the transistor models, the software construction of the simulation compact models, and the engineering challenges of a right-first-time design flow, with notes and references to the current state-of-the-art advances and publications. Real world examples of simulation models, circuit designs, fabricated samples and measurements have also been given demonstrating how the theory can be used in applications.

Available in PDF, EPUB and Kindle. Book excerpt: Ziel dieser Arbeit war die Herstellung und Charakterisierung eines lichtemittierenden ambipolaren organischen Feldeffekttransistors (OFET). In der Literatur wurden lichtemittierende ambipolare Feldeffekttransistoren auf der Basis organischer Moleküle, die von Interesse für neue elektro-optische Bauelemente sind, bisher noch nicht beschrieben. Für die Realisierung eines lichtemittierenden ambipolaren OFETs wurden drei verschiedenene Strategien verfolgt: Zum einen wurden konventionelle Einschichtstrukturen aufihre Elektrolumineszenzeigenschaften hin untersucht. Desweiteren wurden Zweischichtstrukturen auf der Basis eines Elektronen- und eines Löchertransportmaterials hergestellt. Schließlich wurde ein völlig neues Konzept basierend auf koverdampften, d.h. gemischten Filmen bestehend aus Löcher- und Elektronentransportmaterial, realisiert. Die Einschichtstrukturen für sich waren zwar emittierend, doch ist aufgrund der unipolaren Transporteigenschaften der organischen Materialien die Lichtemission auf einen Bereich an einem Kontakt beschränkt. Im Gegensatz dazu wurde an den Zweischichtstrukturen eine ambipolare Transportcharakteristik gemessen, jedoch keine Elektrolumineszenz beobachtet. Schließlich konnte über das neue Konzept der koverdampften Bulk-Heterostruktur erstmals Elektrolumineszenz in einem ambipolaren OFET beobachtet werden. The goal of this thesis was the fabrication and characterization of a light-emitting am- bipolar organic field-effect transistor (OFET). In the literature, light-emitting ambipolar field-effect transistors (FET) based on small molecules, which are of interest for novel electro-optical devices, have not yet been described. For the realization of such a light- emitting ambipolar OFET, three different strategies were pursued: Firstly, conventional single-layer OFETs were investigated in terms of their electroluminescent properties. Secondly, bilayer heterostructures based on an electron- and a hole-transport material were prepared. Thirdly, a novel concept based on coevaporated, i.e. mixed films consisting of an electron- and a hole-transport material, has been realized. Although the single-layer structures were light-emitting, the unipolar transport properties of the organic materials restrict light emission to a region close to one contact. In contrast, in bilayer heterostructures an ambipolar transport characteristics was measured, but no electroluminescence (EL) observed. Finally, with the novel concept of a coevaporated bulk heterostructure, EL in an ambipolar OFET could be observed for the first time.

This book was released on 2009 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic field-effect transistors (FETs) have been widely investigated due to their potential applications in low cost, large area, and flexible electronics. Despite the rapid progress in organic FETs there are still obstacles such as high density of defect in organic semiconductor and poor interface between dielectric and organic semiconductor. In this dissertation, charge transport characteristics of ethyl-hexyl substituted polyfluorene (PF2/6) using hybrid metal-oxide-semiconductor (MOS) structures are presented. Capacitance and conductance-voltage measurements give insight into the presence of distribution of trap charges at the interface. In addition, by thermal annealing of PF2/6 film to a semicrystalline phase, the bulk and interface properties of PF2/6 are significantly improved. Charge storage characteristics of MOS structure containing size tunable sub-2 nm Pt nanoparticles between Al2O3 double layers were studied. Significantly different amounts of memory window were obtained due to the different size of Pt nanoparticles and reached a maximum of 4.3 V using 1.14 nm Pt nanoparticles. Satisfactory long term non-volatility was attained in a low electric field due to the Coulomb blockade and quantum confinement effects in ~1 nm Pt nanoparticle. Further, our metal nanoparticle formation at room temperature can be integrated to polymer dielectric and semiconductor to produce polymer-based non-volatile memory.
