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.

Available in PDF, EPUB and Kindle. Book excerpt: The era of plastic electronics is rapidly emerging due to the increasing development and application of low-cost, printable, shape-conforming, and large-area devices, such as organic field-effect transistors (OFETs) and circuits, organic solar cells, and organic light-emitting devices. Deepening our understanding of charge-carrier dynamics in polymer semiconductors is critical to the future advances in organic electronics. This dissertation focuses on studies of OFETs and aims to better understand the charge transport properties of polymer semiconductors and factors that influence the performance of OFETs. Case studies of structure-morphology-property relationships in unipolar p- and n-channel polymer OFETs as well as ambipolar OFETs reveal that variations in molecular structure and processing affect electronic energy levels, solid-state morphology and crystallinity, and thus the magnitude and polarity of charge carriers. The studies resulted in achievement of high-performance OFETs with high charge-carrier mobility of up to 0.3 cm2/Vs. The morphology and electronic energy levels are also related to ambient stability and durability of polymer OFETs through kinetics and thermodynamics of interaction between the semiconductor and extrinsic molecules in ambient air. Air-stable ambipolar OFETs were realized by utilizing unipolar p- and n-type polymer semiconductors as the active channel elements. Complementary digital logic circuits such as inverters and NAND- and NOR-gates, were also demonstrated using the unipolar and ambipolar OFETs. Device engineering studies show that electron mobility and electrical stability of n-channel polymer OFETs can be significantly enhanced by inserting a low-dielectric-constant polymer dielectric buffer layer at the semiconductor/dielectric interface. Electron mobility was found to increase exponentially with decreasing dielectric constant of the buffer layer. Finally, poly(3-butylthiophene)-nanowire/polystyrene nanocomposites were also investigated as a means of controlling the solid-state morphology of active thin films in OFETs. High dc conductivity and high hole mobility were obtained throughout a wide range of the nanowire compositions (2-100 wt%) due in part to the very low percolation threshold (0.5 wt%).

Download or read book Cross-linked Polymers as Dielectrics for Organic Field-effect Transistors written by Zied Fahem and published by Cuvillier Verlag. This book was released on 2013-11-21 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic electronics are getting more and more interest from industrial companies and research groups in the last years since they enable many new applications, which could not be realized by inorganic materials [1{7]. Flexible displays [1], large-area sensors [1], light-emitting large surfaces [8], printable radio-frequency identification tags (RFID) for packaging or logistic industry [2] and many other systems which require exible, large area and low-cost electronic devices are now developed for the near future or even already commercialized. Organic light-emitting-diode (OLED) displays, for example, are now implemented in portable devices and have higher performance than the traditional LCD displays [9]. OLED displays are self illuminating and do not need back lightening, therefore they have higher brightness, contrast and viewing angle in comparison to LCD displays [9]. Many electronic devices producers implemented OLED displays in their high-end smartphones and SLR cameras [10], and recently LG (a Korean company) introduced a 55-inch OLED television [11]. Large-area solar cells based on organic materials have also found their way to commercialization [12]. All of these innovations were only possible after the introduction of organic conductors and semiconductors. Organic (semi)-conductors have the advantage of their low-cost processing technologies (e.g. printing or spray-coating). However, they have lower electrical conductivity, free charge carriers mobility [13] and packaging density than their inorganic counterparts. Therefore they are normally used in lowcost and low-performance applications, except in the case of OLED where they have clear advantages compared with other technologies. In order to produce fully exible devices, elementary devices for electronic circuits (e.g. transistors and diodes) need to be made with exible materials. The performance of these devices needs to be enhanced and their fabrication processes should be optimized to ensure their commercialization as switching elements in OLED displays or in other circuits. These tasks are principally a material issue, that means new materials with higher performance and easier processability are sought after. Most of the work done in this direction is devoted to synthesize new semiconducting materials with higher mobility and solution-processability. Parallel to these investigations, new dielectric materials with good dielectric properties even in thin films, solution-processability and good interface properties to the semiconductors should be developed. Cross-linked polymers are advantageous for organic field-effect transistors (OFETs) because of their electrical and chemical properties, specially their high volume resistivity and their stability towards solvents, acids and bases. This work shows that the application of cross-linked materials can also reduce or even eliminate the use of the volatile organic compounds (VOC), for which legal limitations are yearly augmented.
Book Synopsis Photo-Excited Charge Collection Spectroscopy by : Seongil Im
Download or read book Photo-Excited Charge Collection Spectroscopy written by Seongil Im and published by Springer Science & Business Media. This book was released on 2014-07-08 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid state field-effect devices such as organic and inorganic-channel thin-film transistors (TFTs) have been expected to promote advances in display and sensor electronics. The operational stabilities of such TFTs are thus important, strongly depending on the nature and density of charge traps present at the channel/dielectric interface or in the thin-film channel itself. This book contains how to characterize these traps, starting from the device physics of field-effect transistor (FET). Unlike conventional analysis techniques which are away from well-resolving spectral results, newly-introduced photo-excited charge-collection spectroscopy (PECCS) utilizes the photo-induced threshold voltage response from any type of working transistor devices with organic-, inorganic-, and even nano-channels, directly probing on the traps. So, our technique PECCS has been discussed through more than ten refereed-journal papers in the fields of device electronics, applied physics, applied chemistry, nano-devices and materials science, finally finding a need to be summarized with several chapters in a short book. Device physics and instrumentations of PECCS are well addressed respectively, in the first and second chapters, for the next chapters addressing real applications to organic, oxide, and nanostructured FETs. This book would provide benefits since its contents are not only educational and basic principle-supportive but also applicable and in-house operational.

This book was released on 2018-12-15 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on essential synaptic plasticity emulations and neuromorphic computing applications realized with the aid of three-terminal synaptic devices based on ion-coupled oxide-based electric-double-layer (EDL) transistors. To replicate the robust, plastic and fault-tolerant computational power of the human brain, the emulation of essential synaptic plasticity and computation of neurons/synapse by electronic devices are generally considered to be key steps. The book shows that the formation of an EDL at the dielectric/channel interface that slightly lags behind the stimuli can be attributed to the electrostatic coupling between ions and electrons; this mechanism underlies the emulation of short-term synaptic behaviors. Furthermore, it demonstrates that electrochemical doping/dedoping processes in the semiconducting channel by penetrated ions from electrolyte can be utilized for the emulation of long-term synaptic behaviors. Lastly, it applies these synaptic transistors in an artificial visual system to demonstrate the potential for constructing neuromorphic systems. Accordingly, the book offers a unique resource on understanding the brain-machine interface, brain-like chips, artificial cognitive systems, etc.
