Electronic Properties of Doped Semiconductors (Springer Series in Solid-State Sciences #45)

by B.I. Shklovskii A.L. Efros

First-generation semiconductors could not be properly termed "doped- they were simply very impure. Uncontrolled impurities hindered the discovery of physical laws, baffling researchers and evoking pessimism and derision in advocates of the burgeoning "pure" physical disciplines. The eventual banish­ ment of the "dirt" heralded a new era in semiconductor physics, an era that had "purity" as its motto. It was this era that yielded the successes of the 1950s and brought about a new technology of "semiconductor electronics". Experiments with pure crystals provided a powerful stimulus to the develop­ ment of semiconductor theory. New methods and theories were developed and tested: the effective-mass method for complex bands, the theory of impurity states, and the theory of kinetic phenomena. These developments constitute what is now known as semiconductor phys­ ics. In the last fifteen years, however, there has been a noticeable shift towards impure semiconductors - a shift which came about because it is precisely the impurities that are essential to a number of major semiconductor devices. Technology needs impure semiconductors, which unlike the first-generation items, are termed "doped" rather than "impure" to indicate that the impurity levels can now be controlled to a certain extent.

It presents most recent results on preparation, experimental analysis by electron spectroscopy, infrared and Raman spectroscopy, luminescence, and nonlinear optical, as well as possible technological applications. Emphasis is also placed on the superconducting properties of Fullerenes. The introductory and advanced contributions provide a good survey of the current status of this rapidly developing field.

Electronic Properties of Graphene Heterostructures with Hexagonal Crystals (Springer Theses)

by John R. Wallbank

The last decade has witnessed the discovery of, and dramatic progress in understanding the physics of graphene and related two-dimensional materials. The development of methods for manufacturing and aligning high-quality two-dimensional crystals has facilitated the creation of a new generation of materials: the heterostructures of graphene with hexagonal crystals, in which the graphene electrons acquire new, qualitatively different properties. This thesis provides a comprehensive theoretical framework in which to understand these heterostructures, based on the tight binding model, perturbation theory, group theory and the concept of the moire superlattice (all of which are elucidated). It explains how graphene heterostructures provide new opportunities for tailoring band structure, such as creating additional Dirac points or opening band gaps and how they manifest themselves in transport measurements, optical absorption spectra and the fractal Hofstadter spectra. Also considered are the heterostructures of bilayer graphene and resonant tunneling in aligned graphene/insulator/graphene devices.

Electronic Properties of High-Tc Superconductors: The Normal and the Superconducting State of High-Tc Materials (Springer Series in Solid-State Sciences #113)

by Hans Kuzmany Michael Mehring Jörg Fink

The International Winter School on Electronic Properties of High-Temperature Superconductors, held between March 7-14, 1992, in Kirchberg, (Tyrol) Austria, was the sixth in a series of meetings to be held at this venue. Four of the earlier meetings were dedicated to issues in the field of conducting polymers, while the winter school held in 1990 was devoted to the new discipline of high-T c superconductivity. This year's meeting constituted a forum not only for the large number of scientists engaged in high-Tc research, but also for those involved in the new and exciting field of fullerenes. Many of the issues raised during the earlier winter schools on conducting polymers, and the last one on high-T c superconductivity, have taken on a new significance in the light of the discovery of superconducting C materials. 60 The Kirchberg meetings are organized in the style of a school where expe­ rienced scientists from universities, research laboratories and industry have the opportunity to discuss their most recent results, and where students and young scientists can learn about the present status of research and applications from some of the most eminent workers in their field. In common with the previous winter school on high-Tc superconductors, the of the cuprate superconductors. present one focused on the electronic properties In addition, consideration was given to related compounds which are relevant to the understanding of the electronic structure of the cuprates in the normal state, to other oxide superconductors and to fulleride superconductors.

Electronic Properties of Inorganic Quasi-One-Dimensional Compounds: Part I — Theoretical (Physics and Chemistry of Materials with B #1)

by P. Monceau

The close relationship between experimentalists and theorists – whether solid state chemists or physicists – has, in the last few years, inspired much research in the field of materials with quasi one-dimensional structures. This volume, Part I of a two-volume set, reviews the basic theories describing the physical properties of one-dimensional materials including their superconducting characteristics. This description is mainly based on the properties of transition metal trichalcogenides. The novel collective transport mechanism for electronic conduction, exhibited by some of the latter compounds – NbSe3 being considered as the prototype – is surveyed according to a classical theory and a theory including macroscopic quantum effects. In addition, the book contains a description of the properties of non-linear excitations, or solitons, in one-dimensional systems.

Electronic Properties of Materials

by Rolf E. Hummel

This text on the electrical, optical, magnetic, and thermal properties of materials stresses concepts rather than mathematical formalism. Suitable for advanced undergraduates, it is intended for materials and electrical engineers who want to gain a fundamental understanding of alloys, semiconductor devices, lasers, magnetic materials, and so forth. The book is organized to be used in a one-semester course; to that end each section of applications, after the introduction to the fundamentals of electron theory, can be read independently of the others. Many examples from engineering practice serve to provide an understanding of common devices and methods. Among the modern applications covered are: high-temperature superconductors, optoelectronic materials, semiconductor device fabrication, xerography, magneto-optic memories, and amorphous ferromagnetics. The fourth edition has been revised and updated with an emphasis on the applications sections, which now cover devices of the next generation of electronics.

Electronic Properties of Materials

by Rolf E. Hummel

It is quite satisfying for an author to learn that his brainchild has been favorably accepted by students as well as by professors and thus seems to serve some useful purpose. This horizontally integrated text on the electronic properties of metals, alloys, semiconductors, insulators, ceramics, and poly­ meric materials has been adopted by many universities in the United States as well as abroad, probably because of the relative ease with which the material can be understood. The book has now gone through several re­ printing cycles (among them a few pirate prints in Asian countries). I am grateful to all readers for their acceptance and for the many encouraging comments which have been received. I have thought very carefully about possible changes for the second edition. There is, of course, always room for improvement. Thus, some rewording, deletions, and additions have been made here and there. I withstood, how­ ever, the temptation to expand considerably the book by adding completely new subjects. Nevertheless, a few pages on recent developments needed to be inserted. Among them are, naturally, the discussion of ceramic (high-tempera­ ture) superconductors, and certain elements of the rapidly expanding field of optoelectronics. Further, I felt that the readers might be interested in learning some more practical applications which result from the physical concepts which have been treated here.

Electronic Properties of Multilayers and Low-Dimensional Semiconductor Structures (Nato Science Series B: #231)

by J. M. Chamberlain L. Eaves J. C. Portal

This Advanced Study Institute on the Electronic Properties of Multilayers and Low Dimensional Semiconductor Structures focussed on several of the most active areas in modern semiconductor physics. These included resonant tunnelling and superlattice phenomena and the topics of ballistic transport, quantised conductance and anomalous magnetoresistance effects in laterally gated two-dimensional electron systems. Although the main emphasis was on fundamental physics, a series of supporting lectures described the underlying technology (Molecular Beam Epitaxy, Metallo-Organic Chemical Vapour Deposition, Electron Beam Lithography and other advanced processing technologies). Actual and potential applications of low dimensional structures in optoelectronic and high frequency devices were also discussed. The ASI took the form of a series of lectures of about fifty minutes' duration which were given by senior researchers from a wide range of countries. Most of the lectures are recorded in these Proceedings. The younger members of the Institute made the predominant contribution to the discussion sessions following each lecture and, in addition, provided most of the fifty-five papers that were presented in two lively poster sessions. The ASl emphasised the impressive way in which this research field has developed through the fruitful interaction of theory, experiment and semiconductor device technology. Many of the talks demonstrated both the effectiveness and limitations of semiclassical concepts in describing the quantum phenomena exhibited by electrons in low dimensional structures.

Electronic Properties of Organic Conductors: An Introduction For Chemists And Engineers

by Takehiko Mori

This book provides an easily understandable introduction to solid state physics for chemists and engineers. Band theory is introduced as an extension of molecular orbital theory, and its application to organic materials is described. Phenomena beyond band theory are treated in relation to magnetism and electron correlation, which are explained in terms of the valence bond theory and the Coulomb and exchange integrals. After the fundamental concepts of magnetism are outlined, the relation of correlation and superconductivity is described without assuming a knowledge of advanced physics. Molecular design of organic conductors and semiconductors is discussed from the standpoint of oxidation-reduction potentials, and after a brief survey of organic superconductors, various applications of organic semiconductor devices are described. This book will be useful not only for researchers but also for graduate students as a valuable reference.

Electronic Properties of Polymers: Orientation and Dimensionality of Conjugated Systems Proceedings of the International Winter School, Kirchberg, (Tyrol) Austria, March 9–16, 1991 (Springer Series in Solid-State Sciences #107)

by Hans Kuzmany Michael Mehring Siegmar Roth

The International Winter School on Electronic Properties of Polymers Orien­ tation and Dimensionality of Conjugated Systems, held March 9-16, 1991, in Kirchberg, ('lYrol) Austria, was a sequel to three meetings on similar subjects held there. The 1991 winter school was again organized in cooperation with the "Bundesministerium fUr Wissenschaft und Forschung" in Austria, and with the "Bundesministerium fUr Forschung und Technologie" in the Federal Republic of Germany. The basic idea of the meeting was to provide an opportunity for experienced scientists from universities and industry to discuss their most re­ cent results and for students and young scientists to become familiar with the present status of research and applications in the field. Like the previous winter schools on polymers, this one concentrated on the electronic structure and potential~ for application of polymers with conjugated double bonds. This time, however, special attention was paid to the effects of orientation and dimensionality. Anisotropy of the electric conductivity in stretch-oriented samples and whether the transport mechanisms are one-, two-, or three-dimensional or might even have a "fractal dimensionality" were there­ fore central topics. The problem of orientation was extended to systems such as Langmuir-Blodgett films and other layered structures. Accordingly, thin films were the focus of most of the application oriented contributions. Whereas in the previous winter schools discussions on applications dealt with "large volume applications" such as electromagnetic shielding and energy storage, this time "molecular materials for electronics" and prospects of "molecular electronics" were at the center of interest.

Electronic Properties of Polymers and Related Compounds: Proceedings of an International Winter School, Kirchberg, Tirol, February 23 – March 1, 1985 (Springer Series in Solid-State Sciences #63)

by H. Kuzmany M. Mehring Siegmar Roth

At the International Winter School on "Electronic Properties of Polymers and Related Compounds" particular attention was paid to a very new and special field in polymer research. It is concerned with the study of the electronic structure of polymers and with physical and chemical properties directly re­ lated to this structure. In particular, tutorial and research contributions on electrical, electrochemical, optical, magnetic, lattice dynamical and structural properties were presented. In addition, review reports on related topics such as charge transfer complexes and linear-chain compounds (transi­ tion-metal trichalcogenides) were included. In two discussion meEjtings, the special role of polyacetylene and possible present and future applications of the electronic properties of polymers, as e.g. conductors or as electrodes in electrochemical cells, were elucidated. The electronic properties of polymers cover a wide range of research problems which are of particular interest for polymers with a 1T-electron system. Thus, a great part of the work presented was concerned with conjuga­ ted systems. Additional presentations dealt with other systems such as bio­ polymers, photopolymers or electrets, which are of significant scientific and technical importance. It was demonstrated how their electronic proper­ ties are increasingly being investigated from a fundamental point of view by applying known concepts of snlid-state science.

Electronic Properties of Rhombohedral Graphite (Springer Theses)

by Servet Ozdemir

This thesis presents the first systematic electron transport investigation of rhombohedral graphite (RG) films and thus lies at the interface of graphene physics, vdW heterostructure devices and topological matter. Electron transport investigation into the rhombohedral phase of graphite was limited to a few layers of graphene due to the competing hexagonal phase being more abundant. This work reports that in exfoliated natural graphite films, rhombohedral domains of up to 50 layers can be found. In the low energy limit, these domains behave as an N-layer generalisation of graphene. Moreover, being a potential alternative to twisted bilayer graphene systems, RG films show a spontaneous metal-insulator transition, with characteristic symmetry properties that could be described by mean-field theory where superconductivity is also predicted in these low energy bands. A nodal-line semimetal in the bulk limit, RG thin films are a 3D generalisation of the simplest topological insulator model: the Su-Schrieffer-Heeger chain. Similar to the more usual topological insulators, RG films exhibit parallel conduction of bulk states, which undergo three-dimensional quantum transport that reflects bulk topology.

Electronic Properties of Surfaces

by M. Prutton

In recent years the availability of techniques and the asking of basic and technological questions has led to an international explosion of activity in the study of solid surfaces. Originally published in Reports in Progress in Physics, Electronic Properties of Surfaces reflects the modern knowledge in this field, presenting critical appraisals of progress in surface science. The book should be particularly valuable for researchers new to this field.

Electronic Publishing for Physics and Astronomy (Astrophysics and Space Science Library #224)

by Andre Heck

The ship has left the Miraflores Locks, let loose from the 'mules' run by the crews of the Panama Canal Commission. She has picked up speed while passing under the Bridge of the Americas which links de facto the Northern and Southern parts of the continent, and has headed resolutely towards the Pacific Ocean waters along the rows of boats of all kinds waiting to cross the Canal in the other direction. Through a layer of tropical clouds, the setting Sun is bleakly illuminating the tall white highrises of Panama City on the port side. It took a full day to cautiously move through the whole system of locks and cuts. Back in the stateroom, I open again a working copy of this book and type down this foreword on the pocket computer. The last chapter was received the day before while speeding through the Caribbean Sea and my main work as Editor is now over. It has been a real pleasure and a great honour to be given the oppor­ tunity of compiling this book and interacting with the various contributors through the latest technologies while being sometimes in geographically very different places. The quality of the authors, the scope of experiences they cover, the messages they convey make of this book a unique and timely publication. The reader will certainly enjoy as much as I did going through such a variety of well-inspired chapters from so many different horizons.

The book is written for graduate students and researchers in the field of mesoscopic semiconductors or in semiconductor nanostructures. Highlights include review of the cryogenic scanning probe techniques applied to semiconductor nanostructures.

Electronic States in Crystals of Finite Size: Quantum Confinement of Bloch Waves (Springer Tracts in Modern Physics #270)

by Shang Yuan Ren

This book presents an analytical theory of the electronic states in ideal low dimensional systems and finite crystals based on a differential equation theory approach. It provides precise and fundamental understandings on the electronic states in ideal low-dimensional systems and finite crystals, and offers new insights into some of the basic problems in low-dimensional systems, such as the surface states and quantum confinement effects, etc., some of which are quite different from what is traditionally believed in the solid state physics community. Many previous predictions have been confirmed in subsequent investigations by other authors on various relevant problems. In this new edition, the theory is further extended to one-dimensional photonic crystals and phononic crystals, and a general theoretical formalism for investigating the existence and properties of surface states/modes in semi-infinite one-dimensional crystals is developed. In addition, there are various revisions and improvements, including using the Kronig-Penney model to illustrate the analytical theory and make it easier to understand. This book is a valuable resource for solid-state physicists and material scientists.

Electronic States in Crystals of Finite Size: Quantum confinement of Bloch waves (Springer Tracts in Modern Physics #212)

by SHANGYUAN REN

The theory of electronic states in crystals is the very basis of modern solid state physics. In traditional solid state physics – based on the Bloch theorem – the theory of electronic states in crystals is essentially a theory of electronic states in crystals of in?nite size. However, that any real crystal always has a ?nite size is a physical reality one has to face. The di?erence between the electronic structure of a real crystal of ?nite size and the electronic structure obtained based on the Bloch theorem becomes more signi?cant as the crystal size decreases. A clear understanding of the properties of electronic states in real crystals of ?nite size has both theoretical and practical signi?cance. Many years ago when the author was a student learning solid state physics at Peking University, he was bothered by a feeling that the general use of the periodic boundary conditions seemed unconvincing. At least the e?ects of such a signi?cant simpli?cation should be clearly understood. Afterward, he learned that many of his school mates had the same feeling. Among many solid state physics books, the author found that only in the classic book Dynamic Theory of Crystal Lattices by Born and Huang was there a more detailed discussion on the e?ects of such a simpli?cation in an Appendix.

Electronic States of Inorganic Compounds: Lectures Presented at the NATO Advanced Study Institute held at the Inorganic Chemistry Laboratory and St. John’s College, Oxford, 8–18 September 1974 (Nato Science Series C: #20)

by Peter R. Day

In the last few years a surprisingly large number of new experimental techniques have been devised to probe, often with great subtlety, into the electronic structures of inorganic substances. Thus in favourable cases one now has the opportunity of locating and assigning electronically excited states over a 1 vast energy range stretching from tens of cm- above the ground 1 6 state up to some 10 cm- • The techniques are extremely dis­ parate in background, involving (among others) linearly and circularly polarised electromagnetic radiation, electron kinetic energy analysis and neutron scattering. Furthermore, practition­ ers of many of the techniques may not be aware of how the information which they are obtaining overlaps and complements that obtained by other techniques. The time therefore seemed ripe to bring together a group of experts to survey, for an audience of inorganic chemists, the basic theories and experim­ ental procedures relevant to the different techniques, and the relations between them. In pursuing this aim we were fortunate in having the very generous financial backing of N. A. T. O. , through their Advanced Study Institutes programme, and the present volume records the substance of lectures given at the Institute which took place at the Inorganic Chemistry Laboratory and St. John's College, Oxford, from 8-18 September 1974.
