Ultrafast Laser Probe Phenomena In Bulk And Microstructure Semiconductors Iii

This volume will contain contributions from researchers who have been associated with Professor Leite's long career in science and science management. After an extremely successful career as a research physicist at Bell Labs, Professor Leite returned to Brazil, where he was instrumental in founding the Institute of Physics of the State University of Campinas. His record in research and scientific leadership, together with his concern with social issues related to Science and Technology, has made him one of the most respected voices of the Brazilian scientific community.The contributions in this volume are centered around Optical Properties of Condensed Matter. However, given the broad spectrum of Professor Leite's activities, it is natural that some authors have contributed papers on other fields.

This book offers an extensive introduction to the extremely rich and intriguing field of spin-related phenomena in semiconductors. In this second edition, all chapters have been updated to include the latest experimental and theoretical research. Furthermore, it covers the entire field: bulk semiconductors, two-dimensional semiconductor structures, quantum dots, optical and electric effects, spin-related effects, electron-nuclei spin interactions, Spin Hall effect, spin torques, etc. Thanks to its self-contained style, the book is ideally suited for graduate students and researchers new to the field.

This volume presents five review articles covering a broad range of topics which will be of interest to many scientists concerned with optics and related subjects.The first article deals with nonlinear optical properties of chalcogenide glasses. These materials have many interesting structural properties, some of which are useful for applications to integrated active optical devices. This article presents a review of experimental measurements of nonlinear absorption coefficients and nonlinear refractive indices of such materials. A review of various models formulated to explain their properties is also included.The next article reviews the research on super-resolution, i.e. the possibility of overcoming the classical diffraction limit of about half a wavelength. The problem is shown to be essentially equivalent to extrapolating the spatial frequency spectrum of the object beyond the spectral band of the optical system.
