Download or read book The Thermoballistic Transport Model written by Reinhard Lipperheide and published by Springer. This book was released on 2014-05-09 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents a comprehensive survey of the thermoballistic approach to charge carrier transport in semiconductors. This semi-classical approach, which the authors have developed over the past decade, bridges the gap between the opposing drift-diffusion and ballistic models of carrier transport. While incorporating basic features of the latter two models, the physical concept underlying the thermoballistic approach constitutes a novel, unifying scheme. It is based on the introduction of "ballistic configurations" arising from a random partitioning of the length of a semiconducting sample into ballistic transport intervals. Stochastic averaging of the ballistic carrier currents over the ballistic configurations results in a position-dependent thermoballistic current, which is the key element of the thermoballistic concept and forms the point of departure for the calculation of all relevant transport properties. In the book, the thermoballistic concept and its implementation are developed in great detail and specific examples of interest to current research in semiconductor physics and spintronics are worked out.
Download or read book High Magnetic Fields in Semiconductor Physics II written by Gottfried Landwehr and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains contributions presented at the International Conference "The Application of High Magnetic Fields in Semiconductor Physics", which was held at the University of Wiirzburg from August 22 to 26, 1988. In the tradition of previous Wiirzburg meetings on the subject - the first conference was held in 1972 - only invited papers were presented orally. All 42 lecturers were asked to review their subject to some extent so that this book gives a good overview of the present state of the respective topic. A look at the contents shows that the subjects which have been treated at previous conferences have not lost their relevance. On the contrary, the application of high magnetic fields to semiconductors has grown substantially during the recent past. For the elucidation of the electronic band structure of semicon ductors high magnetic fields are still an indispensable tool. The investigation of two-dimensional electronic systems especially is frequently connected with the use of high magnetic fields. The reason for this is that a high B-field adds angular momentum quantization to the boundary quantization present in het erostructures and superlattices. A glance at the contributions shows that the majority deal with 2D properties. Special emphasis was on the integral and fractional quantum Hall effect. Very recent results related to the observation of a fraction with an even denbminator were presented. It became obvious that the polarization of the different fractional Landau levels is more complicated than originally anticipated.

This book was released on 2017 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last two decades, spin transistors that operate using both charge and spin properties of electrons have motivated extensive studies of injection, detection and manipulation of electronic spin current in various material systems. Dilute magnetic semiconductors, in which the spin polarized charge carriers are coupled to the magnetic moment, are of particular interest due to their compatible lattice structures and similar growth methods to current Si and GaAs technology. The first part of this thesis focuses on the structural, magnetic and magnetotransport properties of magnetically doped GaN and 2D MoS2. The Gd doped AlN/GaN heterostructures are grown by plasma assisted molecular beam epitaxy. The Gd atoms are [delta]-doped at the AlN/GaN heterointerface where the two dimensional electron gas (2DEG) forms. These samples exhibit defect-induced room temperature ferromagnetism with an easy axis along the c-axis. However, the nonlinear Hall resistivity does not track the magnetization in these Gd doped samples indicating the lack of coupling between the conduction electrons in the 2DEG and the Gd-induced ferromagnetism. This makes Gd doped GaN not useful as a dilute magnetic semiconductor. Mn doped few-layer MoS2 samples synthesized via sulfurization of Mn thin film on sapphire are fabricated in the aim of realizing a 2D dilute magnetic semiconductor. However, these samples mainly show paramagnetism implying the lack of ferromagnetic coupling between the Mn dopants.

This book was released on 2002-04-05 with total page 1224 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Basic Properties of Semiconductors written by P.T. Landsberg and published by Elsevier. This book was released on 2016-04-19 with total page 1219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since Volume 1 was published in 1982, the centres of interest in the basic physics of semiconductors have shifted. Volume 1 was called Band Theory and Transport Properties in the first edition, but the subject has broadened to such an extent that Basic Properties is now a more suitable title. Seven chapters have been rewritten by the original authors. However, twelve chapters are essentially new, with the bulk of this work being devoted to important current topics which give this volume an almost encyclopaedic form. The first three chapters discuss various aspects of modern band theory and the next two analyze impurities in semiconductors. Then follow chapters on semiconductor statistics and on surfaces, interfaces and band offsets as they occur in heterojunctions. Chapters 8 to 19 report on newer topics (though a survey of transport properties of carriers is also included). Among these are transport of hot electrons, and thermoelectric effects including here and elsewhere properties of low-dimensional and mesoscopic structures. The electron-hole liquid, the quantum Hall effect, localisation, ballistic transport, coherence in superlattices, current ideas on tunnelling and on quantum confinement and scattering processes are also covered.

This book was released on 2004-12-13 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to understand and control the unique properties of interfaces has created an entirely new field of magnetism which already has a profound impact in technology and is providing the basis for a revolution in electronics. The last decade has seen dramatic progress in the development of magnetic devices for information technology but also in the basic understanding of the physics of magnetic nanostructures. Volume III describes thin film magnetic properties and methods for characterising thin film structure topics that underpin the present 'spintronics' revolution in which devices are based on combined magnetic materials and semiconductors. The present volume (IV) deals with the fundamentals of spintronics: magnetoelectronic materials, spin injection and detection, micromagnetics and the development of magnetic random access memory based on GMR and tunnel junction devices. Together these books provide readers with a comprehensive account of an exciting and rapidly developing field. The treatment is designed to be accessible both to newcomers and to experts already working in this field who would like to get a better understanding of this very diversified area of research.
Download or read book Resonant Tunneling in Semiconductors written by L.L. Chang and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the NATO Advanced Research Workshop on "Resonant Tunneling in Semiconductors: Physics and Applications", held at Escorial, Spain, on May 14-18, 1990. The tremendous growth in the past two decades in the field of resonant tunneling in semiconductor heterostructures has followed, if not outpaced, the expansion wit nessed in quantum structures in general. Resonant tunneling shares also the multi disciplinary nature of that broad area, with an emphasis on the underlying physics but with a coverage of material systems on the one end and device applications on the other. Indeed, that resonant tunneling provides great flexibility in terms of materials and configurations and that it is inherently a fast process with obvious device impli cations by the presence of a negative differential resistance have contributed to the unrelenting interest in this field. These proceedings consist of 49 refereed articles; they correspond to both invited and contributed talks at the workshop. Because of the intertwinning nature of the subject matter, it has been difficult to subdivide them in well-defined sections. Instead, they are arranged in several broad categories, meant to serve only as guidelines of emphasis on different topics and aspects. The book starts with an introduction to res onant tunneling by providing a perspective of the field in the first article. This is fol lowed by discussions of different material systems with various band-structure effects.
