Magnetic Resonance of Semiconductors and Their Nanostructures : Basic and Advanced Applications Preface Basic Concepts of Electron Paramagnetic Resonance (EPR) Fundamentals of EPR Related Methods Magnetic Resonance Studies of Intrinsic Defects in Semiconductors State of Art: High Frequency EPR ESE ENDOR and ODMR in Wide Band Gap Semiconductors Magnetic Resonance in Semiconductor Micro and Nanostructures Perspectives of Applications of Magnetic Properties of Semiconductor Nanostructures and Single Defects. This book explains different magnetic resonance (MR) techniques and uses different combinations of these techniques to analyze defects in semiconductors and nanostructures. It also introduces novelties such as single defects MR and electron paramagnetic resonance based methods: electron spin echo electrically detected magnetic resonance optically detected magnetic resonance and electron nuclear double resonance – the designated tools for investigating the structural and spin properties of condensed systems living matter nanostructures and nanobiotechnology objects. Further the authors address problems existing in semiconductor and nanotechnology sciences that can be resolved using MR and discuss past current and future applications of MR with a focus on advances in MR methods. The book is intended for researchers in MR studies of semiconductors and nanostructures wanting a comprehensive review of what has been done in their own and related fields of study as well as future perspectives.
