Book Description
Amorphous silicon technology has been the subject of symposia every year since 1984. This remarkable longevity is due to the continuous emergence of new scientific questions and new technological challenges for silicon thin films. Earlier there was a strong emphasis on methods to achieve high deposition rates using plasma or hot-wire chemical vapor deposition, and on the properties and applications of nanocrystalline silicon films, which for example have been incorporated into stacked a-Si:H/nc-Si:H solar cells. The papers appearing in this book are sorted under six chapter headings on the basis of subject matter. Chapter I is concerned with amorphous network structures, electronic metastability, defects, and photoluminescence. Chapter II focuses on thin-film transistors and imager arrays. Chapter III covers solar cells. Chapter IV addresses growth mechanisms, hot-filament CVD, and nc-Si:H growth. Chapter V contains all remaining topics in film growth, especially those related to devices. Finally, Chapter VI focuses on crystallized film.

Book Description
This book celebrates 20 years of MRS symposia on the topic of amorphous silicon. Contributors showed that the simplified theories developed to explain the limited experimental information available in the early eighties have spurred more sophisticated experimentation - either refining the early understanding or making it irrelevant. The differences of opinion that continue to exist and emerge are probably the hallmark of the amazing vitality of this field. Applications range from 'mature' thin-film transistors, solar cells and image sensors, to the 'emerging' possibility of erbium-doped nanocrystalline silicon-based materials for lasers and amorphous silicon quantum dots for luminescent devices. The book discusses material characterization, growth processes and devices. Each chapter is further subdivided into sections that group papers around common themes. Topics include: nanomaterials; electronic structure; metastable effects; understanding of growth processes; laser-induced crystallization; metal-induced crystallization; other growth techniques; newer devices; solar cells and thin-film transistors.

Book Description
Fifty-eight peer-reviewed papers from the December 2003 symposium examine questions of structure, properties, and processing of amorphous and nanocrystalline materials. Organized into six sessions, the broad topics covered within this area of materials science include crystallization of amorphous alloys, quasicrystals from metallic glasses, processing and glass forming ability, physical properties, shear bands and mechanical properties, and applications and environmental effects.

Book Description
This handbook is a compendium giving a comprehensive description of the basics of semiconductor physics relevant to the design and analysis of thin film solar cell materials. It starts from the basics of material science, describing the material and its growth, defect and electrical properties, the basics of its interaction with photons and the involved statistics, proceeding to space charge effects in semiconductors and pn-junctions. Most attention is given to analyze homo- and hetero-junction solar cells using various models and applying the field-of-direction analysis for discussing current voltage characteristics, and helping to discover the involvement of high-field effects in solar cells. The comprehensive coverage of the main topics of - and relating to - solar cells with extensive reference to literature helps scientists and engineers at all levels to reach a better understanding and improvement of solar cell properties and their production. The author is one of the founders of thin film solar cell research.

Book Description
The measure of a thermoelectric material is given by the material's figure of merit. For over three decades the best thermoelectric materials had a ZT = 1. Recently, however, there are reports of new methods of materials synthesis that result in improvements beyond this performance. In addition, rapid characterization, as well as faster theoretical modeling of thermoelectric materials, has resulted in a more rapid evaluation of new materials. This book offers a look at these results and provides a benchmark for the current state in the field of thermoelectric materials research and development. The focus is on new and innovative directions that will lead to the next generation thermoelectric materials for small-scale refrigeration and power generation applications. The book emphasizes the multidisciplinary nature of the research needed to advance the science and technology of the field. Both theoretical and experimental studies are featured. Topics include: low-dimensional systems and nanocomposites; devices; oxides; skutterudites; complex bulk materials and measurements; novel approaches; and thermoelectric materials and technology.

Book Description
Twenty years after the discovery of a quasicrystalline compound, the field of quasicrystals still raises interest and is continuously evolving. Quasicrystals display properties different from conventional crystals with small unit cells and present interesting potential for industrial purposes. This book offers an updated look into the field of quasicrystalline research. For example, a report on electrodeposited Al-Cu-Fe quasicrystals shows great promise for industry. It is also demonstrated that when Al-Cu-Fe quasicrystals are used as catalysts, in particular at high temperatures, such quasicrystals outperform conventional industrial catalysts. A new class of quasicrystal, based on a novel type of local order differing from previously observed Mackay- and Bergman-type quasicrystals, is featured. A detailed description of layer-by-layer growth of a Cu film on a quasicrystalline surface is also provided. Additional topics include: synthesis and structure; transport properties; electronic properties; mechanical properties; quasicrystals from metallic glasses; surfaces and coatings; and applications and hydrogen storage.

Book Description
The availability of materials that can bind selectively to a target molecule is the key to unlocking a host of new technologies. Molecular imprinting is an established technology, which allows the synthesis of materials containing highly specific receptor sites having an affinity for a target compound. For example, molecularly imprinted materials can mimic some of the functions of enzymes through the creation of three-dimensional cavities of specific size and shape for biorecognition of bioactive compounds. This volume offers a forum for technical exchange among members of the worldwide community of scientists and engineers who work in the area of molecular imprinting. Researchers from academia, government and industry present results in applications of molecular imprinting related to catalysis, combinatorial and computational methods, new monomers and recognition strategies, sensors, drug discovery and therapy, and new molecular imprinting formats.

Book Description
This book focuses on recent advances in nanostructured and nanophase materials and their applications. Nanostructured materials consist of domains of less than 100nm and include atom clusters and cluster assemblies, one- and two-dimensionally modulated layers and three-dimensional structures. The term 'nanophase' refers to structures comprised of domains or particles of a single material that are typically less than 100nm, whereas 'nanocomposite' refers to a composite of more than one nanophase. Nanoscale materials can be engineered as homogeneous or porous ceramics, metals, metal oxides, semiconductors, organic polymers, or as composite materials containing these components. This book brings together scientists from many disciplines to share and discuss advances in the field. Topics include: nanophase materials; nanocomposite materials; nanoporous materials; nanostructured materials; applications and properties of nanostructured materials; carbon nanotubes; nanostructured thin films and coatings; and theoretical and modeling studies of nanostructured materials.
