Disordered Solids
Author: Baldassare Di Bartolo
Publisher: Springer Science & Business Media
ISBN: 1468454757
Category : Science
Languages : en
Pages : 439
Book Description
This book presents an account of the course "Disordered Solids: Structures and Processes" held in Erice, Italy, from June 15 to 29, 1987. This meeting was organized by the International School of Atomic and Molecular Spectroscopy of the "Ettore Majorana" Centre for Scientific Culture. The objective of this course was to present the advances in physical modelling, mathematical formalism and experimental techniques relevant to the interpretation of the structures of disordered solids and of the physical processes occurring therein. Traditional solid-state physics treats solids as perfect crystals and takes great advantage of their symmetry, by means of such mathematical formalisms as the reciprocal lattice, the Brillouin zone, and the powerful tools of group theory. Even if in reality no solid is a perfect crystal, this theoretical approach has been of great usefulness in describing solids: deviations from perfect order have been treated as perturbations of the ideal model. A new situation arises with truly disordered solids where any vestige of long range order has disappeared. The basic problem is that of describing these systems and gaining a scientific understanding of their physical properties without the mathematical formalism of traditional solid state physics. While some of the old approaches may occasionally remain valid (e. g. chemical bonding approach for amorphous solids), the old ways will not do. Disorder is not a perturbation: with disorder, something basically new may be expected to appear.

Survey of Semiconductor Physics, Electronic Transport in Semiconductors
Author: Karl W. Böer
Publisher: Wiley-VCH
ISBN:
Category : Science
Languages : en
Pages : 1224
Book Description
A comprehensive treatment of the fundamentals of semiconductor physics and materials science. The first edition of the Survey of Semiconductor Physics set the standard for the multifaceted exploration of semiconductor physics. Now, Dr. Karl B?er, one of the world's leading experts in solid-state physics, with assistance from a team of the fields top researchers, expands this coverage in the Second Edition. Completely updated and substantially expanded, the Survey of Semiconductor Physics, Second Edition covers the basic elements in the entire field of semiconductor physics, emphasizing the materials and surface science involved. The Second Edition uses similar theoretical approaches and analyses for the basic material classes: crystalline, amorphous, quantum structures, and organics. The first volume provides thorough coverage of the structure of semiconductors, including: Phonons Energy bands Photons as they interact with the semiconductor and other particles Defects Generation and recombination Kinetics Part I of the Volume 2 begins with a thorough treatment of the carrier transport in homogeneous semiconductors, creating the context for the studies of inhomogeneous semiconductors that consume the majority of the text. The editors' primary concerns are the effects and implications of surfaces, interfaces, inhomogeneous doping, and space charges upon the electronic transport. Part II provides a general overview of the types of abrupt material inhomogeneities that are produced by interfaces and surfaces. Part III presents a detailed mathematical analysis of the interrelation between space charges, fields, and carrier transport, applying these calculations to a wide array of specific examples. Returning to his stated emphasis on practical application, B?er then focuses on the material preparations that are essential to produce semiconductor devices in Part IV and examines two specific examples of semiconductors-solar cells and light-emitting diodes-in Part V. In both volumes, extensive appendices simplify searches for important formulae and tables. An elaborate word index and reference listings allow readers to use the reference in multiple ways to discover expanding literature; to explore similarities and connecting principles in other fields; to find out how others in adjacent fields came up with intriguing solutions to similar problems; and to obtain a broad overview of the entire field of semiconductor physics.

Introduction to Thin Film Transistors
Author: S.D. Brotherton
Publisher: Springer Science & Business Media
ISBN: 3319000020
Category : Technology & Engineering
Languages : en
Pages : 467
Book Description
Introduction to Thin Film Transistors reviews the operation, application and technology of the main classes of thin film transistor (TFT) of current interest for large area electronics. The TFT materials covered include hydrogenated amorphous silicon (a-Si:H), poly-crystalline silicon (poly-Si), transparent amorphous oxide semiconductors (AOS), and organic semiconductors. The large scale manufacturing of a-Si:H TFTs forms the basis of the active matrix flat panel display industry. Poly-Si TFTs facilitate the integration of electronic circuits into portable active matrix liquid crystal displays, and are increasingly used in active matrix organic light emitting diode (AMOLED) displays for smart phones. The recently developed AOS TFTs are seen as an alternative option to poly-Si and a-Si:H for AMOLED TV and large AMLCD TV applications, respectively. The organic TFTs are regarded as a cost effective route into flexible electronics. As well as treating the highly divergent preparation and properties of these materials, the physics of the devices fabricated from them is also covered, with emphasis on performance features such as carrier mobility limitations, leakage currents and instability mechanisms. The thin film transistors implemented with these materials are the conventional, insulated gate field effect transistors, and a further chapter describes a new thin film transistor structure: the source gated transistor, SGT. The driving force behind much of the development of TFTs has been their application to AMLCDs, and there is a chapter dealing with the operation of these displays, as well as of AMOLED and electrophoretic displays. A discussion of TFT and pixel layout issues is also included. For students and new-comers to the field, introductory chapters deal with basic semiconductor surface physics, and with classical MOSFET operation. These topics are handled analytically, so that the underlying device physics is clearly revealed. These treatments are then used as a reference point, from which the impact of additional band-gap states on TFT behaviour can be readily appreciated. This reference book, covering all the major TFT technologies, will be of interest to a wide range of scientists and engineers in the large area electronics industry. It will also be a broad introduction for research students and other scientists entering the field, as well as providing an accessible and comprehensive overview for undergraduate and postgraduate teaching programmes.

Physics of Thin-Film Photovoltaics

Publisher: John Wiley & Sons
ISBN: 1119651174
Category : Science
Languages : en
Pages : 288
Book Description
PHYSICS OF THIN-FILM PHOTOVOLTAICS Tackling one of the hottest topics in renewables, thin-film photovoltaics, the authors present the latest updates, technologies, and applications, offering the most up-to-date and thorough coverage available to the engineer, scientist, or student. It appears rather paradoxical that thin-film photovoltaics (PVs) are made of materials that seem unacceptable from the classical PV perspective, and yet they often outperform classical PV. This exciting new volume solves that paradox by switching to a new physics paradigm. Many concepts here fall beyond the classical PV scope. The differences lie in device thinness (microns instead of millimeters) and morphology (non-crystalline instead of crystalline). In such structures, the charge carriers can reach electrodes without recombination. On the other hand, thin disordered structures render a possibility of detrimental lateral nonuniformities (“recombination highways”), and their energy spectra give rise to new recombination modes. The mechanisms of thermal exchange and device degradation are correspondingly unique. The overall objective of this book is to give a self-contained in-depth discussion of the physics of thin-film systems in a manner accessible to both researchers and students. It covers most aspects of the physics of thin-film PV, including device operations, material structure and parameters, thin-film junction formation, analytical and numerical modeling, concepts of large area effects and lateral non-uniformities, physics of shunting (both shunt growth and effects), and device degradation. Also, it reviews a variety of physical diagnostic techniques proven with thin-film PV. Whether for the veteran engineer or the student, this is a must-have for any library. This outstanding new volume: Covers not only the state-of-the-art of thin-film photovoltaics, but also the basics, making this volume useful not just to the veteran engineer, but the new-hire or student as well Offers a comprehensive coverage of thin-film photovoltaics, including operations, modeling, non-uniformities, piezo-effects, and degradation Includes novel concepts and applications never presented in book format before Is an essential reference, not just for the engineer, scientist, and student, but the unassuming level of presentation also makes it accessible to readers with a limited physics background Is filled with workable examples and designs that are helpful for practical applications Is useful as a textbook for researchers, students, and faculty for understanding new ideas in this rapidly emerging field Audience: Industrial professionals in photovoltaics, such as engineers, managers, research and development staff, technicians, government and private research labs; also academic and research universities, such as physics, chemistry, and electrical engineering departments, and graduate and undergraduate students studying electronic devices, semiconductors, and energy disciplines
