Written by an outstanding, well-recognized expert in the field, this book introduces the electrochemical and synthetic methods, as well as characterization techniques and applications for porous silicon. It discusses the construction and considerations involved with etch cells, and describes the three types of porous silicon structures, films, three-dimensional structures, and nanoparticles. Separate chapters consider the measurement of infrared spectra, optical properties, pore size, porosity, thickness, and surface area. The whole is backed by a generous use of color photographs to illustrate the described procedures in detail, plus a bibliography of further literature pertinent to a wide range of application fields.
