Available in PDF, EPUB and Kindle. Book excerpt: The challenge for producing “invisible” electronic circuitry and opto-electronic devices is that the transistor materials must be transparent to visible light yet have good carrier mobilities. This requires a special class of materials having “contra-indicated properties” because from the band structure point of view, the combination of transparency and conductivity is contradictory. Structured to strike a balance between introductory and advanced topics, this monograph juxtaposes fundamental science and technology / application issues, and essential materials characteristics versus device architecture and practical applications. The first section is devoted to fundamental materials compositions and their properties, including transparent conducting oxides, transparent oxide semiconductors, p-type wide-band-gap semiconductors, and single-wall carbon nanotubes. The second section deals with transparent electronic devices including thin-film transistors, photovoltaic cells, integrated electronic circuits, displays, sensors, solar cells, and electro-optic devices. Describing scientific fundamentals and recent breakthroughs such as the first “invisible” transistor, Transparent Electronics: From Synthesis to Applications brings together world renowned experts from both academia, national laboratories, and industry.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Consumer-driven demand for affordable, smaller and more sophisticated devices has driven advances in nanoscale engineering. Many of these products, whether they are consumer electronics, fuel cells or photovoltaics, are comprised of significant quantities of scarce, expensive and sometimes toxic materials. Manufacturing affordable and more environmentally benign products on decreasing length scales requires more economical use of scarce resources and the exploration of alternative and abundant materials. Platinum, as one example, is an outstanding catalyst used in automotive, fine chemical and fuel cell applications; however, it is extremely scarce and costly. Placing platinum only where needed and in small quantities to achieve desired performance may help economize its usage. Because nanoscale feature size and spacing influence catalytic behavior, being able to control these parameters may enable the careful engineering of more powerful platinum catalysts. Another scarce and expensive material whose usage follows rising consumer demand for electronics and photovoltaics is indium. Indium tin oxide is the industry standard transparent conducting oxide (TCO) for high-end electronics. The engineering of high-quality yet poorly-understood indium-free alternative metal oxides using earth-abundant and inexpensive materials may further the development of more powerful and advanced devices. In this dissertation, atomic layer deposition (ALD), a promising ultra-thin film growth technique, is used to selectively deposit small amounts of platinum and to alloy zinc tin oxide in order to address these concerns of scarcity and rising costs. ALD consists of self-limiting, gas-surface half-reactions separated by inert gas purges which allows for highly controlled growth of nanoscale materials. Because ALD is based on surface reactions, selectively blocking nucleation sites by passivating growth surfaces allows for the deposition of material only where desired. The spatial deposition of platinum using ALD is demonstrated in two studies. In the first, a water-soluble polymer, polymethacrylamide (PMAM) acts as a resist to ALD and allowed the deposition of very small features of platinum. In the second study, surface passivation by means of controlling defect site density in self-assembled monolayers (SAMs) also serves as a growth template to control the aerial density and size of platinum nanoparticles deposited via ALD. The highly tunable nature of the chemistry of each precursor half-reaction in ALD enables the careful alloying or doping of materials in any desired ratio. A range of compositions for the indium-free TCO alternative, zinc tin oxide (ZTO), is explored by varying the dosing cycle ratios of tin oxide (SnOx) and zinc oxide (ZnO) in each ALD super cycle. Because the effects of ZTO composition on conduction behavior and optical properties are not well understood, having nanoscale control over how the constituent metal oxides grow on one another is an effective approach to learning more about these properties. As a result, ALD is explored as a flexible system to allow for compositional sampling and variation of film lamination in ZTO. The characteristics of ZTO ALD and the structural and optical properties of these films were shown to vary significantly as a function of degree of lamination and composition. These findings suggest that having nanoscale control over these film characteristics via ALD can lead to further understanding of ZTO. The ALD of ZTO provides an excellent system for the nanoengineering of this material as an indium-free TCO or buffer layer in solar cells.

Book excerpt: Atomic layer deposition (ALD) is a thin film deposition process renowned for its ability to produce layers with unrivaled control of thickness and composition, conformability to extreme three-dimensional structures, and versatility in the materials it can produce. These range from multi-component compounds to elemental metals and structures with compositions that can be adjusted over the thickness of the film. It has expanded from a small-scale batch process to large scale production, also including continuous processing – known as spatial ALD. It has matured into an industrial technology essential for many areas of materials science and engineering from microelectronics to corrosion protection. Its attributes make it a key technology in studying new materials and structures over an enormous range of applications. This Special Issue contains six research articles and one review article that illustrate the breadth of these applications from energy storage in batteries or supercapacitors to catalysis via x-ray, UV, and visible optics.

This book was released on 2011-11-16 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today’s solar cell multi-GW market is dominated by crystalline silicon (c-Si) wafer technology, however new cell concepts are entering the market. One very promising solar cell design to answer these needs is the silicon hetero-junction solar cell, of which the emitter and back surface field are basically produced by a low temperature growth of ultra-thin layers of amorphous silicon. In this design, amorphous silicon (a-Si:H) constitutes both „emitter“ and „base-contact/back surface field“ on both sides of a thin crystalline silicon wafer-base (c-Si) where the electrons and holes are photogenerated; at the same time, a-Si:H passivates the c-Si surface. Recently, cell efficiencies above 23% have been demonstrated for such solar cells. In this book, the editors present an overview of the state-of-the-art in physics and technology of amorphous-crystalline heterostructure silicon solar cells. The heterojunction concept is introduced, processes and resulting properties of the materials used in the cell and their heterointerfaces are discussed and characterization techniques and simulation tools are presented.

Download or read book Chemical Solution Deposition of Functional Oxide Thin Films written by Theodor Schneller and published by Springer Science & Business Media. This book was released on 2014-01-24 with total page 801 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first text to cover all aspects of solution processed functional oxide thin-films. Chemical Solution Deposition (CSD) comprises all solution based thin- film deposition techniques, which involve chemical reactions of precursors during the formation of the oxide films, i. e. sol-gel type routes, metallo-organic decomposition routes, hybrid routes, etc. While the development of sol-gel type processes for optical coatings on glass by silicon dioxide and titanium dioxide dates from the mid-20th century, the first CSD derived electronic oxide thin films, such as lead zirconate titanate, were prepared in the 1980’s. Since then CSD has emerged as a highly flexible and cost-effective technique for the fabrication of a very wide variety of functional oxide thin films. Application areas include, for example, integrated dielectric capacitors, ferroelectric random access memories, pyroelectric infrared detectors, piezoelectric micro-electromechanical systems, antireflective coatings, optical filters, conducting-, transparent conducting-, and superconducting layers, luminescent coatings, gas sensors, thin film solid-oxide fuel cells, and photoelectrocatalytic solar cells. In the appendix detailed “cooking recipes” for selected material systems are offered.
