Книга Correlation Spectroscopy of Surfaces, Thin Films, and Nanostructures Correlation Spectroscopy of Surfaces, Thin Films, and NanostructuresКниги Физика Автор: Jamal Berakdar, Jürgen Kirschner Год издания: 2004 Формат: pdf Издат.:Wiley-VCH Страниц: 255 Размер: 6,5 ISBN: 3527404775 Язык: Английский0 (голосов: 0) Оценка:Here, leading scientists present an overview of the most modern experimental and theoretical methods for studying electronic correlations on surfaces, in thin films and in nanostructures. In particular, they describe in detail coincidence techniques for studying many-particle correlations whilecritically examining the informational content of such processes from a theoretical point viewpoint. Furthermore, the book considers the current state of incorporating many-body effects into theoretical approaches.Covered topics:-Auger-electron photoelectron coincidence experiments and theories-Correlated electron emission from atoms, fullerens, clusters, metals and wide-band gap materials-Ion coincidence spectroscopies and ion scattering theories from surfaces-GW and dynamical mean-field approaches-Many-body effects in electronic and optical response
