Although porous silicon is rapidly attracting increasing interest in various fields, there is currently no up to date general introduction to basic properties and potential applications. Until now. This book focuses on the fundamentals of silicon porosification and properties of porous silicon, including electrical, luminescence, optical, thermal properties. Processing of porous silicon also will be discussed in this part. Comprehensive and up to date, this is a technical resource and guide for all those involved in the research, development and application of porous silicon in various areas of science and technology.
