This book is review of the different aspects and concepts related to the optical properties of semiconductors. It bridges the dielectric constant concept and the more recent experimental investigations. In particular, the optical response function to time-resolved, high energy, Raman spectroscopies are reviewed. New results focusing on the properties of correlated electrons are also discussed in detail, with a special emphasis on magnetic field-induced properties. As a result of these advanced investigations, this book provides up-to-date reviews of the principles and performances of semiconductor-based light detectors and emitters. The book is dedicated to graduates and young scientists who would like to have a general view of the fundamental and technical aspects of the optical properties of semiconductors.

This book is a significant contribution to the state of the art in the field of computational bioengineering — from the need for a living human database to meshless methods in biomechanics, from computational mechanobiology to the evaluation of stresses in hip prosthesis replacement, from lattice Boltzmann methods for analyzing blood flow to the analysis of fluid movement in long bones, among other interesting topics treated herein. Well-known international experts in bioengineering have contributed to the book, giving it a unique style and cutting-edge material for graduate students, academic researchers and design bioengineers, as well as those interested in getting a better understanding of such complex and fascinating human and living processes.

It is widely recognized that an understanding of the optical pro­ perties of matter will give a great deal of important information re­ levant to the fundamental physical properties. This is especially true in semiconductor physics for which, due to the intrinsic low screening of these materials, the optical response is quite rich. Their spectra reflect indeed as well electronic as spin or phonon transitions. This is also in the semiconductor field that artificial structures have been recently developed, showing for the first time specific physical properties related to the low dimentionality of the electronic and vi­ bronic properties : with this respect the quantum and fractional quan­ tum Hall effects are among the most well known aspects. The associated reduced screening is also a clear manifestation of these aspects and as such favors new optical properties or at least significantly enhan­ ces some of them. For all these reasons, it appeared necessary to try to review in a global way what the optical investigation has brought today about the understanding of the physics of semiconductors. This volume collects the papers presented at the NATO Advanced study Inst i tut e on "Optical Properties of Semiconductors" held at the Ettore Majorana Centre, Erice, Sicily on March 9th to 20th, 1992. This school brought together 70 scientists active in research related to optical properties of semiconductors. There were 12 lecturers who pro­ vided the main contributions .
