Book Description
This book provides fundamental and practical information on all aspects of GaAs processing and gives pragmatic advice on cleaning and passivation, wet and dry etching and photolithography. Other topics covered include device performance for HBTs (Heterojunction Bipolar Transistors) and FETs (Field Effect Transistors), how these relate to processing choices, and special processing issues such as wet oxidation, which are especially important in optoelectronic devices. This book is suitable for both new and practising engineers.

Book Description
Knowledge of the refractive indices and absorption coefficients of semiconductors is especially import in the design and analysis of optical and optoelectronic devices. The determination of the optical constants of semiconductors at energies beyond the fundamental absorption edge is also known to be a powerful way of studying the electronic energy-band structures of the semiconductors. The purpose of this book is to give tabulated values and graphical information on the optical constants of the most popular semiconductors over the entire spectral range. This book presents data on the optical constants of crystalline and amorphous semiconductors. A complete set of the optical constants are presented in this book. They are: the complex dielectric constant (E=e.+ieJ, complex refractive index (n*=n+ik), absorption coefficient (a.), and normal-incidence reflectivity (R). The semiconductor materials considered in this book are the group-IV elemental and binary, llI-V, IT-VI, IV-VI binary semiconductors, and their alloys. The reader will fmd the companion book "Optical Properties of Crystalline and Amorphous Semiconductors: Materials and Fundamental Principles" useful since it emphasizes the basic material properties and fundamental prinCiples.

Book Description
The communications industry is at the onset of new expansion of WDM technology necessary to meet the new demand for bandwidth. This is the second of a four reference books that will cover this technology comprehensively with all of the major topics covered by a separate volumes - i.e. active components, passive components, systems and networks. This book is the first which covers all key passive optical components required for current and next generation optical communication systems. World-renowned authors, who are pioneers in their research area, have written the chapters in their area of expertise. The book highlights not only the principle of operation and characteristics of the passive optical components, but also provides an in-depth account of the state-of-the-art system applications.- Helps the reader to choose the right device for a given system application.- Provides the reader with insight and understanding for key passive optical components frequently being / to be used in the optical communication systems, essential building blocks of today's/next generation fiber optic networks.- Allows engineers working in different optical communication areas(i.e. from system to component), to understand the principle and mechanics of each key component they deal with for optical system design.- Covers Planar lightwave circuit (PLC) based router, different optical switches technologies (based on MEMS, thermo-optic, and electro-optic) and different optical amplifier technologies (based on semiconductor optical amplifier, EDFA ,and raman amplifier). - Highlights the operating principle of each component, system applications, and also future opportunities.

Book Description
les Houches This Winter School on "The Physics and Fabrication of Microstructures" originated with a European industrial decision to investigate in some detail the potential of custom-designed microstructures for new devices. Beginning in 1985, GEC and THOMSON started a collaboration on these subjects, supported by an ESPRIT grant from the Commission of the European Com munity. To the outside observer of the whole field, it appears clear that the world effort is very largely based in the United States and Japan. It also appears that cooperation and dissemination of results are very well organised outside Europe and act as a major influence on the development of new concepts and devices. In Japan, a main research programme of the Research and Development for Basic Technology for Future Industries is focused on "Future Electron Devices". In Japan and in the United States, many workshops are organised annually in order to bring together the major specialists in industry and academia, allowing fast dissemination of advances and contacts for setting up cooperative efforts.

Book Description
This book provides a detailed study of the Atomic Layer Epitaxy technique (ALE), its development, current and potential applications. The rapid development of coating technologies over the last 25 years has been instrumental in generating interest and expertise in thin films of materials, and indeed the market for thin film coatings is currently £3 billion with projected annual growth of 20 to 30% [1]. ALE is typical of thin-film processes in that problems in the processing or preparation of good quality epitaxial films have been overcome, resulting in better performance, novel applications of previously unsuitable materials, and the development of new devices. Many materials exhibit interesting and novel properties when prepared as thin films and doped. Vapour-deposited coatings and films are used extensively in the semiconductor and related industries for making single devices, integrated circuits, microwave hybrid integrated circuits, compact discs, solar reflective glazing, fibre optics, photo voltaic cells, sensors, displays, and many other products in general, everyday use. The ALE technique was developed by a research team led by Tuomo Suntola, working for Instrumentarium Oy in Finland. The key members of this team were lorma Antson, Arto Pakkala and Sven Lindfors. In 1977, the research team moved from Instrumentarium to Lohja Corporation, where they continued the development of ALE and were granted a patent in the same year. By 1980, the technique was sufficiently advanced that they were producing flat-screen electroluminescent displays based on a manganese-doped zinc sulphide layer.

[From" Dittamondo", by Fazio degli UbertiJ Heterojunction interfaces, the interfaces between different semiconducting materi als, have been extensively explored for over a quarter of a century.
