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 work of 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 for the extraction of various TFT parameters like the threshold voltage, field effect mobility, sub threshold slope and on-off ratio, etc. will be ready for those working in the field of transparent electronics.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Zinc oxide (ZnO) thin films have great promise for a wide range of optoelectronic applications, however controlling crystallinity and stoichiometry at low processing temperatures remains a challenge. Pulsed laser deposition (PLD) is a versatile technique that allows precise control the film properties. The crystallinity and electrical properties can, theoretically, be tuned by altering a wide variety of deposition parameters. However, until now there has been little work performed exploring PLD as a technique for the preparation of thin films at low temperature, for use in optoelectronic applications. In this thesis, PLD is demonstrated as a highly appropriate technique for the preparation of semiconducting and electrically conducting transparent films, over a wide range of substrate temperatures applicable for optoelectronic grade substrates. Deposition conditions are identified allowing the low temperature deposition of ZnO directly onto functional organic poly(3-hexylthiophene) (P3HT) coated substrates. To demonstrate the applicability of this methodology the preparation of conventional architecture hybrid (inorganic:organic) photovoltaic devices is outlined with no degradation to the microstructure, optical or electrical properties of the P3HT observed. The methodology is widely applicable for depositing oxide interlayers multilayer organic devices. In this thesis, the role of ZnO is investigated as i) an exciton dissociation and electron transporting layer in hybrid devices, ii) an optical spacing layer in organic bulk heterojunction photovoltaic devices and iii) as a transparent conducting oxide (when doped with A1) as a top contact for organic optoelectronic devices. Device performance is optimised through careful control of PLD parameters. In each device and in free-standing thin films the microstructure, morphology and crystallographic nature of the as-deposited ZnO is studied by scanning electron microscopy (SEM), atomic force microscopy (AFM) and X-ray diffraction (XRD). The electrical properties are studied in both operational devices and by 4-point probe measurements.

Download or read book Nanoliquid Processes for Electronic Devices written by Tatsuya Shimoda and published by Springer. This book was released on 2019-02-05 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the results of the research on how to make small electronic devices with high properties by using simple liquid processes such as coating, self-assembling and printing, especially focusing on devices composed of silicon and oxide materials. It describes syntheses and analyses of solution materials, formations of solid thin films from solutions, newly developed patterning methods to make devices, and characterization of the developed devices. In the first part of the book, the research on liquid silicon (Si) materials is described. Because the use of a liquid material is a quite new idea for Si devices, this book is the first one to describe liquid Si materials for electronic devices. Si devices as typified by MOS-FET have been produced by using solid and gas materials. This volume precisely describes a series of processes from material synthesis to device fabrication for those who are interested and are/will be engaged in liquid Si-related work. In the latter part of the book, a general method of how to make good oxide films from solutions and a new imprinting method to make nanosized patterns are introduced. For making oxide films with high quality, the designing of the solution is crucial. If a solution is designed properly, a gel material called "cluster gel" can be formed which is able to be imprinted to form nanosized patterns. The anticipated readers of this book are researchers, engineers, and students who are interested in solution and printing processes for making devices. More generally, this book will also provide guidelines for corporate managers and executives who are responsible for making strategies for future manufacturing processes.

Available in PDF, EPUB and Kindle. Book excerpt: Pulsed ultraviolet light from a XeF excimer laser was used to grow thin films of zinc oxide and tin dioxide on (111) p-type silicon wafers within a versatile high vacuum laser deposition system. This pulsed laser deposition system was self-designed and self-built. Parameters such as pressure, target temperature, and distance from the target to the substrate can be adjusted in the system. Scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction spectroscopy, Raman spectroscopy and ellipsometry were used to analyze the structures and properties of ZnO and SnO2 thin films. The critical temperature required to fabricate a crystalline ZnO thin film by pulsed laser deposition was found and has been confirmed. For the SnO2 thin film, the critical temperature required to generate a crystalline structure could not be found because of the temperature limit of the substrate heater used in the experiment. In SnO2 thin films, thermal annealing has been used to convert into crystalline structure with (110), (101) and (211) orientations. After fabricating the amorphous SnO2 thin films, they were put into an oven with specific temperatures to anneal them. The minimum annealing temperature range was found for converting the amorphous SnO2 thin films into SnO2 thin films with a crystalline structure. Thermal annealing has also been applied to some amorphous ZnO thin films which were fabricated under the critical temperature required to produce crystalline ZnO thin films. The minimum annealing temperature range for amorphous ZnO thin films was found and only one orientation (002) shown after annealing. Laser annealing technology has also been applied for converting both amorphous ZnO and SnO2 thin films, and results show that this method was not well suited for this attempt. ZnO thin films and SnO2 thin films with a crystalline structure have inportant widely used in industry, for example, application in devices such as solar cells and UV or blue-light-emitting devices. The aim of this research is to help improving the manufacturing process of ZnO and SnO2 thin films.
