This book is focused on the spintronic properties of III–V nitride semiconductors. Particular attention is paid to the comparison between zinc blende GaAs- and wurtzite GaN-based structures, where the Rashba spin–orbit interaction plays a crucial role in voltage-controlled spin engineering. The book also deals with topological insulators, a new class of materials that could deliver sizable Rashba spin splitting in the surface electron spectrum. Electrically driven zero-magnetic-field spin splitting of surface electrons is discussed with respect to the specifics of electron-localized spin interaction and voltage-controlled ferromagnetism. The book covers generic topics in spintronics without entering into device specifics, since the overall goal of the enterprise is to provide theoretical background for most common concepts of spin-electron physics and give instructions to be used in solving problems of a general and specific nature. The book is intended for graduate students and may serve as an introductory course in this specific field of solid-state theory and applications.

This new volume focuses on a new, exciting field of research: Spintronics, the area also known as spin-based electronics. The ultimate aim of researchers in this area is to develop new devices that exploit the spin of an electron instead of, or in addition to, its electronic charge. In recent years many groups worldwide have devoted huge efforts to research of spintronic materials, from their technology through characterization to modeling. The resultant explosion of papers in this field and the solid scientific results achieved justify the publication of this volume. Its goal is to summarize the current level of understanding and to highlight some key results and milestones that have been achieved to date. Semiconductor spintronics is expected to lead to a new generation of transistors, lasers and integrated magnetic sensors that can be used to create ultra-low power, high-speed memory, logic and photonic devices. In addition, development of novel devices such as spin-polarized light emitters, spin field effect transistors, integrated sensors and high-temperature electronics is anticipated. Spintronics has emerged as one of the fastest growing areas of research This text presents an in-depth examination of the most recent technological spintronic developments Includes contributions from leading scholars and industry experts

Spintronics demands precise control of the storage, manipulation, and transfer of electron spin coherence in solid state systems. In particular, the manipulation of spins in semiconductor materials has become an active area of investigation, where the two main challenges are the enhancement of the electron spin coherence times and the development of spin manipulation techniques that do not compromise the spin lifetime.The book begins with a brief historical introduction about the discover of phenomena of both the giant magnetoresistance and the tunneling magnetoresistance, followed by discussions on the importance of electron spin in semiconductor applications. Moreover, the concepts of spin coherence and spin-coupling are introduced. Section 1 focuses on the properties of dilute magnetic semiconductors and ferromagnetic semiconductors, where in particular, the effect of electric field, a first-principles study and hybrid ferromagnet-semiconductor nanostructures are considered. Section 2 discusses of Rashba/Dresselhaus effects and optical responses of electron spins in semiconductors, with special deepening about the probing of spin splittings by photogalvanic spectroscopy, and electron spin detection by magneto-optical Kerr microscopy. Section 3 present recent works about dynamics, manipulation and transport of spin-polarized electron in magnetic wide-bandgap semiconductors, in III-V semiconductor low dimensional structures and in carbon nanotubes.

Rare Earth and Transition Metal Doping of Semiconductor Material explores traditional semiconductor devices that are based on control of the electron’s electric charge. This book looks at the semiconductor materials used for spintronics applications, in particular focusing on wide band-gap semiconductors doped with transition metals and rare earths. These materials are of particular commercial interest because their spin can be controlled at room temperature, a clear opposition to the most previous research on Gallium Arsenide, which allowed for control of spins at supercold temperatures. Part One of the book explains the theory of magnetism in semiconductors, while Part Two covers the growth of semiconductors for spintronics. Finally, Part Three looks at the characterization and properties of semiconductors for spintronics, with Part Four exploring the devices and the future direction of spintronics. Examines materials which are of commercial interest for producing smaller, faster, and more power-efficient computers and other devices Analyzes the theory behind magnetism in semiconductors and the growth of semiconductors for spintronics Details the properties of semiconductors for spintronics
