Download or read book Theoretical Modelling of Semiconductor Surfaces written by G. P. Srivastava and published by World Scientific. This book was released on 1999 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: The state-of-the-art theoretical studies of ground state properties, electronic states and atomic vibrations for bulk semiconductors and their surfaces by the application of the pseudopotential method are discussed. Studies of bulk and surface phonon modes have been extended by the application of the phenomenological bond charge model. The coverage of the material, especially of the rapidly growing and technologically important topics of surface reconstruction and chemisorption, is up-to-date and beyond what is currently available in book form. Although theoretical in nature, the book provides a good deal of discussion of available experimental results. Each chapter provides an adequate list of references, relevant for both theoretical and experimental studies. The presentation is coherent and self-contained, and is aimed at the postgraduate and postdoctoral levels.
Download or read book Quantized Semiconductor Structures written by Lairenlakpam Joyprakash Singh and published by LAP Lambert Academic Publishing. This book was released on 2015-04-08 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on the theoretical study of low dimensional quantum effect devices having quantum confinements in one- two- and three- dimensions of the wave vector space such as quantum wells, metal oxide semiconductor field effect transistors, quantum wires, quantum dots, magnetic quantization, magneto quantum size effects, magnetic inversion layers, superlattices, quantum confined superlattices and field assisted transport in nanodevices. The electron transport in semiconductor devices is essentially determined by their respective band structures. Thus, the nature of the electronic properties become different in the aforementioned systems and varies with the magnitude of the quantizing magnetic field, the quantizing electric field and other types of quantum confined structures. Though various aspects of degenerate electron gases have extensively been reported, nevertheless, it appears from the literature that few other electronic properties of quantized structures have still greater promise for future research work. Keeping this in view, the author undertook theoretical investigations of few electronic properties of quantized semiconductor structures and related phenomena.

Download or read book Symmetry and Symmetry Breaking in Semiconductors written by Bernd Hönerlage and published by Springer. This book was released on 2018-09-19 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses group theory investigations of zincblende and wurtzite semiconductors under symmetry-breaking conditions. The text presents the group theory elements required to develop a multitude of symmetry-breaking problems, giving scientists a fast track to bypass the need for recalculating electronic states. The text is not only a valuable resource for speeding up calculations but also illustrates the construction of effective Hamiltonians for a chosen set of electronic states in crystalline semiconductors. Since Hamiltonians have to be invariant under the transformations of the point group, the crystal symmetry determines the multiplet structure of these states in the presence of spin-orbit, crystal-field, or exchange interactions. Symmetry-breaking leads to additional coupling of the states, resulting in shifts and/or splittings of the multiplets. Such interactions may be intrinsic, as in the case of the quasi-particle dispersion, or extrinsic, induced by magnetic, electric, or strain fields. Using a power expansion of the perturbations these interaction terms can be determined in their parameterized form in a unique way. The hierarchic structure of this invariant development allows to estimate the importance of particular symmetry-breaking effects in the Hamiltonian. A number of selected experimental curves are included to illustrate the symmetry-based discussions, which are especially important in optical spectroscopy. This text is written for graduate students and researchers who want to understand and simulate experimental findings reflecting the fine structure of electronic or excitonic states in crystalline semiconductors.
Download or read book Theoretical Studies of the Electronic Structure of Metal Semiconductor Hydrogen Systems written by and published by . This book was released on 1991 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cesium, hydrogen and oxygen adsorption on beryllium clusters are studied using restricted Hartree-Fock (RHF) calculations and ab initio relativistic effective core potentials. The clusters are taken as cylindrical plugs from beryllium wafers. Cs( - ), H( - ) and 0-to-substrate internuclear distances are optimized. For each system numerous low-lying electronic states are investigated and Mulliken electron populations analyzed. RHF calculations show that Be19, with three layers of atoms, is too small to adequately model the Be surface, while Be33, a five-layered system, and Be45, a seven-layered system, are more accurate representations of the bulk metal. The emitted electron is clearly seen as vacating a molecular orbital which is localized in the surface layer of the cluster, thereby giving further credence to the model. RHF calculations are completed for Pbl and Bil semiconductor clusters. Blue shifts in optical spectra and geometry changes are shown to be due to quantum size effects. Scanning tunneling microscopy is used to investigate the nature of colloidal particles in the 15 nm diameter size range. Images show a near monodispersion of small gold clusters. A model of the STM tip as a polyatomic crystalline surface is shown to correctly explain observations of anomalous long range order.

This book was released on 2011-08-11 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last couple of decades, high-performance electronic and optoelectronic devices based on semiconductor heterostructures have been required to obtain increasingly strict and well-defined performances, needing a detailed control, at the atomic level, of the structural composition of the buried interfaces. This goal has been achieved by an improvement of the epitaxial growth techniques and by the parallel use of increasingly sophisticated characterization techniques and of refined theoretical models based on ab initio approaches. This book deals with description of both characterization techniques and theoretical models needed to understand and predict the structural and electronic properties of semiconductor heterostructures and nanostructures. Comprehensive collection of the most powerful characterization techniques for semiconductor heterostructures and nanostructures Most of the chapters are authored by scientists that are among the top 10 worldwide in publication ranking of the specific field Each chapter starts with a didactic introduction on the technique The second part of each chapter deals with a selection of top examples highlighting the power of the specific technique to analyze the properties of semiconductors

Available in PDF, EPUB and Kindle. Book excerpt: The aim of the contributions in this volume is to give a current overview on the basic properties and applications of semiconductor and nonlinear optical materials for optoelectronics and integrated optics. They provide a cross-linkage between different materials (III-V, II-VI, Si-Ge, glasses, etc.), various sample dimensions (from bulk crystals to quantum dots), and a range of techniques for growth (LPE to MOMBE) and for processing (from surface passivation to ion beams). Major growth techniques and materials are discussed, including the sophisticated technologies required to exploit the exciting properties of low dimensional semiconductors. These proceedings will prove an invaluable guide to the current state of optoelectronic and nonlinear optical materials development, as well as indicating trends and also future markets for optoelectronic devices.

This book was released on 2012-12-02 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Containing over 200 papers, this volume contains the proceedings of two symposia in the E-MRS series. Part I presents a state of the art review of the topic - Carbon, Hydrogen, Nitrogen and Oxygen in Silicon and in Other Elemental Semiconductors. There was strong representation from the industrial laboratories, illustrating that the topic is highly relevant for the semiconductor industry. The second part of the volume deals with a topic which is undergoing a process of convergence with two concerns that are more particularly application oriented. Firstly, the advanced instrumentation which, through the use of atomic force and tunnel microscopies, high resolution electron microscopy and other high precision analysis instruments, now allows for direct access to atomic mechanisms. Secondly, the technological development which in all areas of applications, particularly in the field of microelectronics and microsystems, requires as a result of the miniaturisation race, a precise mastery of the microscopic mechanisms.
Download or read book Theory of Electron Transport in Semiconductors written by Carlo Jacoboni and published by Springer. This book was released on 2011-07-23 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book originated out of a desire to provide students with an instrument which might lead them from knowledge of elementary classical and quantum physics to moderntheoreticaltechniques for the analysisof electrontransport in semiconductors. The book is basically a textbook for students of physics, material science, and electronics. Rather than a monograph on detailed advanced research in a speci?c area, it intends to introduce the reader to the fascinating ?eld of electron dynamics in semiconductors, a ?eld that, through its applications to electronics, greatly contributed to the transformationof all our lives in the second half of the twentieth century, and continues to provide surprises and new challenges. The ?eld is so extensive that it has been necessary to leave aside many subjects, while others could be dealt with only in terms of their basic principles. The book is divided into ?ve major parts. Part I moves from a survey of the fundamentals of classical and quantum physics to a brief review of basic semiconductor physics. Its purpose is to establish a common platform of language and symbols, and to make the entire treatment, as far as pos- ble, self-contained. Parts II and III, respectively, develop transport theory in bulk semiconductors in semiclassical and quantum frames. Part IV is devoted to semiconductor structures, including devices and mesoscopic coherent s- tems. Finally, Part V develops the basic theoretical tools of transport theory within the modern nonequilibrium Green-function formulation, starting from an introduction to second-quantization formalism.
