Opis

Semiconducting and Insulating Crystals details how absorption spectroscopy provides information on the nature, concentration, charge state and configuration of impurities in crystals and also on their kinetics and transformations under annealing. After an introduction of the bulk optical properties of semiconductors and insulators and of impurities in crystals, this book presents the physical bases necessary for the understanding of impurity spectra. The description of various set-ups and accessories used in absorption spectroscopy is followed by a presentation of experimental results on specific impurities and classes of impurities and their relation with those obtained by various computation and by other experimental techniques.

Recenzje

From the reviews:

"Provide a comprehensive and up to date overview of the field. ... the book constitutes a valuable resource for linking the development of materials characterization for micro and opto electronics with the new needs of the growing photovoltaic industry. ... a very useful manual for researchers from graduate to higher levels and for experimentalists who want to enter the subject. ... The books should find a place in the bookshelf of every researcher interested in semiconductor materials and devices ... ." (S. Sanguinetti, Il Nuovo Saggiatore, Vol. 27 (1-2), 2011)

Blurb

Absorption spectroscopy provides information on the chemical nature, atomic structure and concentration of hydrogen-like centers, to which belong most of the dopants of semiconductors and insulators. In this book, an introduction to the bulk optical properties of these materials and to the properties of hydrogen-like centers is first provided, followed by a description of set-ups used in absorption spectroscopy. The results of the calculations of the energy levels of these centres by effective-mass theory are exposed. Detailed absorption data on specific classes of centres are compared with theory, and atomic structures are deduced from absorption measurements under external perturbations.
