Book excerpt: This volume, number 91 in the Semiconductor and Semimetals series, focuses on defects in semiconductors. Defects in semiconductors help to explain several phenomena, from diffusion to getter, and to draw theories on materials' behavior in response to electrical or mechanical fields. The volume includes chapters focusing specifically on electron and proton irradiation of silicon, point defects in zinc oxide and gallium nitride, ion implantation defects and shallow junctions in silicon and germanium, and much more. It will help support students and scientists in their experimental and theoretical paths. - Expert contributors - Reviews of the most important recent literature - Clear illustrations - A broad view, including examination of defects in different semiconductors

Download or read book Crystalline Semiconducting Materials and Devices written by Paul N. Butcher and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is concerned primarily with the fundamental theory underlying the physical and chemical properties of crystalIine semiconductors. After basic introductory material on chemical bonding, electronic band structure, phonons, and electronic transport, some emphasis is placed on surface and interfacial properties, as weil as effects of doping with a variety of impurities. Against this background, the use of such materials in device physics is examined and aspects of materials preparation are discussed briefty. The level of presentation is suitable for postgraduate students and research workers in solid-state physics and chemistry, materials science, and electrical and electronic engineering. Finally, it may be of interest to note that this book originated in a College organized at the International Centre for Theoretical Physics, Trieste, in Spring 1984. P. N. Butcher N. H. March M. P.

Download or read book Point Defects in Semiconductors and Insulators written by Johann-Martin Spaeth and published by Springer Science & Business Media. This book was released on 2003-01-22 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: The precedent book with the title "Structural Analysis of Point Defects in Solids: An introduction to multiple magnetic resonance spectroscopy" ap peared about 10 years ago. Since then a very active development has oc curred both with respect to the experimental methods and the theoretical interpretation of the experimental results. It would therefore not have been sufficient to simply publish a second edition of the precedent book with cor rections and a few additions. Furthermore the application of the multiple magnetic resonance methods has more and more shifted towards materials science and represents one of the important methods of materials analysis. Multiple magnetic resonances are used less now for "fundamental" studies in solid state physics. Therefore a more "pedestrian" access to the meth ods is called for to help the materials scientist to use them or to appreciate results obtained by using these methods. We have kept the two introduc tory chapters on conventional electron paramagnetic resonance (EPR) of the precedent book which are the base for the multiple resonance methods. The chapter on optical detection of EPR (ODEPR) was supplemented by sections on the structural information one can get from "forbidden" transitions as well as on spatial correlations between defects in the so-called "cross relaxation spectroscopy". High-field ODEPR/ENDOR was also added. The chapter on stationary electron nuclear double resonance (ENDOR) was supplemented by the method of stochastic END OR developed a few years ago in Paderborn which is now also commercially available.

Download or read book Dopants and Defects in Semiconductors written by Matthew D. McCluskey and published by CRC Press. This book was released on 2012-02-23 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dopants and Defects in Semiconductors covers the theory, experimentation, and identification of impurities, dopants, and intrinsic defects in semiconductors. The book fills a crucial gap between solid-state physics and more specialized course texts. The authors first present introductory concepts, including basic semiconductor theory, defect classifications, crystal growth, and doping. They then explain electrical, vibrational, optical, and thermal properties. Moving on to characterization approaches, the text concludes with chapters on the measurement of electrical properties, optical spectroscopy, particle-beam methods, and microscopy. By treating dopants and defects in semiconductors as a unified subject, this book helps define the field and prepares students for work in technologically important areas. It provides students with a solid foundation in both experimental methods and the theory of defects in semiconductors.

Download or read book Shallow Impurity Centers in Semiconductors written by A. Baldereschi and published by Elsevier. This book was released on 2012-12-02 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shallow Impurity Centers in Semiconductors presents the proceedings of the Second International Conference on Shallow Impurity Centers/Fourth Trieste IUPAP-ICTP Semiconductor Symposium, held at the International Center for Theoretical Physics in Trieste, Italy, on July 28 to August 1, 1986. The book presents the perspectives of some of the leading scientists in the field who address basic physical aspects and device implications, novel phenomena, recent experimental and theoretical techniques, and the behavior of impurities in new semiconductor materials. Organized into 22 chapters, the book begins with an overview of the early years of shallow impurity states before turning to a discussion of progress in spectroscopy of shallow centers in semiconductors since 1960. It then looks at theoretical and experimental aspects of hydrogen diffusion and shallow impurity passivation in semiconductors, along with optical excitation spectroscopy of isolated double donors in silicon. The book methodically walks the reader through recent research on double acceptors using near-, mid-, and far-infrared spectroscopy, the far-infrared absorption spectrum of elemental shallow donors and acceptors in germanium, and impurity spectra in stress-induced uniaxial germanium using Zeeman spectroscopy. Other papers focus on the theoretical properties of hydrogenic impurities in quantum wells, lattice relaxations at substitutional impurities in semiconductors, shallow bound excitons in silver halides, and the electronic structure of bound excitons in semiconductors. The book concludes with a chapter that reviews picosecond spectroscopy experiments performed in III-V compounds and alloy semiconductors. This volume will be useful to physicists and researchers who are working on shallow impurity centers in semiconductor physics.

She retired in 2017 and currently has an honorary position at the Open University. She has produced OU teaching texts in chemistry for courses at levels 1, 2, and 3 and written texts in astronomy at level 2 and physics at level 3. She was team leader for the production and presentation of an Open University level 2 chemistry module delivered entirely online. She is a Fellow of the Royal Society of Chemistry and a Senior Fellow of the Higher Education Academy. She was co-chair for the successful Departmental submission of an Athena Swan bronze award. Lesley E. Smart studied chemistry at Southampton University, United Kingdom. After completing a PhD in Raman spectroscopy, she moved to a lectureship at the (then) Royal University of Malta. After returning to the United Kingdom, she took an SRC Fellowship to Bristol University to work on X-ray crystallography. From 1977 to 2009, she worked at the Open University chemistry department as a lecturer, senior lecturer, and Molecular Science Programme director, and she held an honorary senior lectureship there until her death in 2016.
