Available in PDF, EPUB and Kindle. Book excerpt: Transparent flexible electronics is an emerging technology which makes use of wide band gap semiconductors that can be processed at low temperatures on glass or plastic substrates. Electronic systems that cover large area and curved surfaces together with transparency bring the possibility of numerous applications that are outside the scope of rigid wafer based electronics. Flexible electronics, electronic textiles, a wearable wellness system, and sensory skin are some of the applications of flexible electronics. The key factor in the realization of transparent electronics is the development of high performance fully transparent thin film transistors. Thin film transistors (TFTs) based on transparent conducting amorphous oxide semiconductors (TAOS) such as InGaZnO (IGZO), zinc tin oxide (ZTO), zinc indium tin oxide (ZITO), etc. provide additional functionalities like transparency, high field effect mobility and potential for room temperature processing. The performance of these TAOS based TFTs are superior to their silicon (a-Si:H TFTs) and organic TFTs. Though there are monographs and books on a-Si:H TFTs and organic TFTs, a book on TAOS based TFTs is rare. This book introduces the graduate students and beginners to the field of amorphous semiconductors. The mass production of this kind of TFTs on large area substrates involves the complications associated with controlling the composition of oxide compound semiconductor thin film material. Pulsed laser deposition allows for the growth of an oxide semiconductor in a very high oxygen rich environment while co-sputtering is an effective technique for the growth of a multicomponent film and to control the film chemical composition in a systematic and easy way. These manufacturing aspects will be of interest to those working in the industry. The review on the n channel, p channel TFTs, and the detailed description on the extraction of various TFT parameters like the threshold voltage, field effect mobility, sub threshold slope and on-off ratio etc. will be ready reckoner to those working in the field of transparent electronics.

This book was released on 2011 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amorphous oxide semiconductors are of potential interest in the display industry due to their high carrier mobility, transparency at visible wavelengths and excellent operational stability. In this dissertation, n-channel zinc-tin oxide thin-film transistors are fabricated based on a solution-based deposition approach, which allows low fabrication cost and high throughput. The effects of device configuration and process conditions on transistor performance are investigated, and circuit applications including inverters, amplifiers, and ring oscillators are demonstrated. Charge transport in the zinc-tin oxide field-effect transistors is also investigated. A transition from thermally-activated to band-like transport is observed with increasing carrier concentration in high mobility samples, which agrees well with the key predictions of the multiple trap and release model and also Mott's mobility edge model. In addition, velocity distribution of charge carriers is studied with a time-resolved technique. This provides a more detailed picture of charge transport in field-effect transistors. P-channel organic semiconductor field-effect transistors are also investigated with a view to combine them with n-channel amorphous oxide transistors to create a hybrid organic-inorganic complementary technology.

Available in PDF, EPUB and Kindle. Book excerpt: The focus of this thesis involves development of highly transparent, n-channel, accumulation- mode thin-film transistors employing a zinc tin oxide (ZTO) channel layer. ZTO-based transparent thin-film transistors (TTFTs) show improved device performance compared to ZnO-based TTFTs. An estimated peak effective mobility for these devices as high as ~100 cm2 V−1sec−1 has been observed, although effective mobilities in the range of 20-50 cm2V−1sec−1 are more common. This performance inconsistency may be due, in part, to the large device dimensions employed in developmental test structures and/or to shadow mask misalignment. Typical drain current on-to-off ratios are> 106. Variation in the post-deposition annealing cycle is found to be an effective means to control the threshold voltage and to improve device performance. Optical characterization of these devices indicates ~84% transparency in the visible spectrum as viewed through the source/drain. Another aspect of this thesis research involves the utilization and extension of quantitative polycrystalline TFT device models with the intention of guiding the design and optimization of future TFTs. In particular, subthreshold conduction is assessed in order to estimate the bulk (and/or grain boundary) and interface trap densities. This leads to a consideration of threshold voltage and channel mobility extraction, as well as establishment of the turn-on voltage, V[subscript turn-on] Finally, a third aspect of this thesis research involves a new radio-frequency (RF) magnetron sputtering system, custom-designed and constructed at OSU by Chris Tasker. Contributions to the development of this tool include assisting in the design and implementation of the computer-controlled interlocks utilized for operation of the tool. The experimental flexibility of this new tool is discussed with respect to its applicability in the design and fabrication of future TTFTS.

Available in PDF, EPUB and Kindle. Book excerpt: In this volume, we have collected a series of reviews that cover both experimental and theoretical work geared toward the more exact requirements of current SFE applications. While we have artificially divided the volume into experimental and theoretical sections, natural overlaps will be apparent. Many of the papers on experimental and theoretical sections, natural overlaps will be apparent. Many of the papers on experimental technique contain discussions on equation of state correlations. Indeed, a good deal of the experimental work is intimately tied to a mathematical description of fluid mixtures. The theoretical section presents reviews that cover the modern theory of critical phenomena, methods to correlate near critical experimental results and approaches to understanding the behavior of near critical fluids from microscopic theory. It is hoped that the scope of these reviews will provide the reader with the basis to further develop our understanding of the behavior of supercritical fluids.

This book was released on 2013-12-21 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supercritical Fluid Technology for Energy and Environmental Applications covers the fundamental principles involved in the preparation and characterization of supercritical fluids (SCFs) used in the energy production and other environmental applications. Energy production from diversified resources — including renewable materials — using clean processes can be accomplished using technologies like SCFs. This book is focused on critical issues scientists and engineers face in applying SCFs to energy production and environmental protection, the innovative solutions they have found, and the challenges they need to overcome. The book also covers the basics of sub- and supercritical fluids, like the thermodynamics of phase and chemical equilibria, mathematical modeling, and process calculations.A supercritical fluid is any substance at a temperature and pressure above its critical point where distinct liquid and gas phases do not exist. At this state the compound demonstrates unique properties, which can be "fine-tuned," making them suitable as organic solvents in a range of industrial and laboratory processes.This volume enables readers to select the most appropriate medium for a specific situation. It helps instructors prepare course material for graduate and postgraduate courses in the area of chemistry, chemical engineering, and environmental engineering. And it helps professional engineers learn supercritical fluid-based technologies and use them in solving the increasingly challenging environmental issues. - Relates theory, chemical characteristics, and properties of the particular supercritical fluid to its various applications - Covers the fundamentals of supercritical fluids, like thermodynamics of phase and chemical equilibria, mathematical modeling, and process calculations - Includes the most recent applications of supercritical fluids, including energy generation, materials synthesis, and environmental protection
