Optical absorption of impurities and defects in semiconducting crystals: electronic absorption of deep centres and vibrational spectra

This book outlines, with the help of several specific examples, the importantrole played by absorption spectroscopy in the investigation of deep-level centers introduced in semiconductors and insulators like diamond, silicon, germanium and gallium arsenide by high-energy irradiation, residual impurities, and defects produced during crystal growth. It also describes the crucial role played by vibrational spectroscopy to determine the atomic structure and symmetryof complexes associated with light impurities like hydrogen, carbon, nitrogenand oxygen, and as a tool for quantitative analysis of these elements in the materials. Reviews optical absorption of impurities and defects in semiconductors. Establishes a correlation between electronic, vibrational spectroscopy and electron spin resonance. Displays numerous spectroscopic data on isotope effects inquasimonoisotopic crystals. Discusses spectroscopic results in natural and synthetic diamond. INDICE: Foreword. Preface. Notations and symbols. Introduction. Bulk optical absorption. Instrumental methods for absorption spectroscopy. Absorption ofdeep centres and bound excitons. Vibrational absorption of substitutional atoms and related centres. Vibrational absorption of interstitial atoms and related centres. Vibrational absorption III. Quasi substitutional atoms and relatedcentres. Vibrational spectra related to hydrogen.
