Semiconductors And The Information Revolution

Semiconductors and the Information Revolution sets out to explain the development of modern electronic systems and devices from the viewpoint of the semiconductor materials (germanium, silicon, gallium arsenide and many others) which made them possible. It covers the scientific understanding of these materials and its intimate relationship with their technology and many applications. It began with Michael Faraday, took off in a big way with the invention of the transistor at Bell Labs in 1947 and is still burgeoning today. It is a story to match any artistic or engineering achievement of man and this is the first time it has been presented in a style suited to the non-specialist. It is written in a lively, non-mathematical style which brings out the excitement of discovery and the fascinating interplay between the demands of system pull and technological push. It also looks at the nature of some of the personal interactions which helped to shape the modern technological world. An introductory chapter illustrates just how dependent we are on modern electronic systems and explains the significance of semiconductors in their development. It also provides, in as painless a way as possible, a necessary understanding of semiconductor properties in relation to these applications. The second chapter takes up the historical account and ends with some important results emerging from the Second World War – including its effect on the organisation of scientific research. Chapter three describes the world-shaking discovery of the transistor and some of the early struggles to make it commercially viable, including the marketing of the first transistor radio. In chapter four we meet the integrated circuit which gave shape to much of our modern life in the form of the personal computer (and which gave rise to a famously long-running patent war!). Later chapters cover the application of compound semiconductors to light-emitting devices, such as LEDs and lasers, and light detecting devices such as photocells. We learn how these developments led to the invention of the CD player and DVD recorder, how other materials were applied to the development of sophisticated night vision equipment, fibre optical communications systems, solar photovoltaic panels and flat panel displays. Similarly, microwave techniques essential to our modern day love of mobile phoning are seen to depend on clever materials scientists who, not for the first time, "invented" new semiconductors with just the right properties. Altogether, it is an amazing story and one which deserves to be more widely known. Read this book and you will be rewarded with a much deeper understanding and appreciation of the technological revolution which shapes so many aspects of our lives. A historical account of the development of semiconductor physics, devices and applications from the nineteenth century to the present day Coverage of the importance of material quality and its relation to the physics of the devices Presented in a strictly non-mathematical and anecedotal way, to appeal to a wide audience Provides the broad sweep of science history

A basic contribution to the discussion of semiconductor electronics, the major technology of our age.

J.-E. Dubois and N. Gershon This book was inspired by the Symposium on "Communications and Computer Aided Systems" held at the 14th International CODATA Conference in September 1994 in Chambery, France. It was conceived and influenced by the discussions at the symposium and most of the contributions were written following the Conference. This is the first comprehensive book, published in one volume, of issues concerning the challenges and the vital impact of the information revolution (including the Internet and the World Wide Web) on science and technology. Topics concerning the impact of the information revolution on science and technology include: • Dramatic improvement in sharing of data and information among scientists and engineers around the world • Collaborations (on-line and off-line) of scientists and engineers separated by distance . • Availability of visual tools and methods to view, understand, search, and share information contained in data • Improvements in data and information browsing, search and access and • New ways of publishing scientific and technological data and information. These changes have dramatically modified the way research and development in science and technology are being carried out. However, to facilitate this information flow nationally and internationally, the science and technology communities need to develop and put in place new standards and policies and resolve some legal issues.

A collection of reprinted articles from various sources discussing the philosophical, cultural, political, and economic consequences of the information revolution.

Tremendous technological progress in the last half century has exponentially grown productivity as well as increased automation to reduce the costs of operation for businesses. On one hand, ever-growing productivity has reduced requirements for manual labor through automation. But, on other hand, huge unemployment created from reduction of workforce due to automaÂtion, has reduced the consumer purchasing power and is indirectly hurting the Return on Investments (RoI). This brings any further progress of technology to a standstill. For technology to progress both supply and demand have to grow. The supply comes from producÂtivity of workforce and demand comes from their wages. Hence, free markets must ensure that wages automatically catch up with ever-growing productivity, with minimal government inÂtervention. To avoid automation from destroying jobs in an economy, free markets should ensure that working hours of workforce be reduced during the waning phase of economy and increased during its waxing phase.

This book considers the potential of new, smart materials and their use in architecture. It begins with an overview of current global tendencies (technological, demographic, and socio-anthropological) and their relevance for architectural design. Expanding upon approaches for flexible design solutions to address change and uncertainty, Dr. Kretzer begins by exploring adaptive architecture and proceeds to introduce the topic of “information materials,” which encompasses smart and functional materials, their current usage, and their potential for the creation of future spaces. The second chapter provides a comprehensive overview of architectural materials, past and present, split into the topics: natural, industrial, synthetic, digital, and information materials. Chapter three introduces an educational approach for the mediation of information material usage in design courses and student workshops. The final section provides detailed information on a range of emerging material phenomena, including aerogels, bioluminescence, bio plastics, dye-sensitized solar cells, electroluminescent displays, electroactive polymers, soft robotics, and thermochromics. Each section explains its respective history, working principles, fabrication and (potential) usage in architecture and design, and provides hands-on tutorials on how to self-produce these materials, and displays class-tested experimental installations. The book concludes with an outlook into the domain of synthetic biology and the prospects of a “living” architecture. It is ideal for students of structural materials engineering, architecture, and urban planning; professionals working these in areas, as well as materials science/engineering and architecture educators.

This report discusses the information revolution in the Asia-Pacific region and its likely course over the next five to ten years. Key questions addressed in this report include the extent to which the information revolution has taken hold of markets in this region, the political implications of the information revolution for Asian governments, the variations between individual countries, and the prospects for further information-technology-related developments in the region.
