Electronic Structure and Optical Properties of Semiconductors : Springer : 9783540513919 : 3540513914 : 14 Sep 1989 : We began planning and writing this book in thc late 1970$ at thc ugge s stion of Manuel Cardona and Helmut Latsch. We also received considerable eo­ couragement and stimulation from colleagues. Same said there was a need for instructional material in tbis area while others emphasized thc utility of a research text. We tried to strike a compromise. Thc figures, tables, and rcferences are included to enable researchcrs to obt81o quickly essential information in this area of semiconductor research. For instructoTS and stu­ dents, we attempt to cover same basic ideas abaut electronic structure and semiconductor physics with applications to real, rather than model, solids. ~Ve \Vish to thank our colleagues and collaborators whose research rc­ sults and ideas are presented here. Special thanks are duc to Jim Phillips who illfluellced lIS hoth during ollr formative )'ears and
