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.

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.

Few books exist that cover the hot field of second-generation spintronic devices, despite their potential to revolutionize the IT industry.Compiling the obstacles and progress of spin-controlled devices into one source, Spintronic Materials and Technology presents an in-depth examination of the most recent technological spintronic developments. Featuring contributions from active researchers and leading experts, the book chronicles the main research challenges in spintronics. It first depicts the different classes of materials systems currently under investigation for use in spintronic devices. The contributors also address issues concerning the operation of spintronic devices, such as the new principle for future devices that use spin-polarized current. This promises to enable switching of individual spin components of the device while avoiding crosstalk at the nanoscale. The book concludes with descriptions of both Si and III-V semiconductor-based spin transistors and the integration of spin technology with photonics. The second-generation spintronic devices discussed in Spintronic Materials and Technology will not only improve the existing capabilities of electronic transistors, but will enable future computers to run faster and consume less power.

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

Recent developments in semiconductor materials and quantum structures are leading to significant advances in optoelectronic devices such as mid-infrared lasers and light-emitting diodes; long-wavelength detectors and solar cells; and modulators and optical switches. Brought to maturity, such devices would likely see widespread use in applications as diverse as infrared imaging, chemical and biological sensing, surveillance, short-links, space-based applications, solar cells, high-bandwidth communications, and many others. This volume highlights the progress in both naturally-and artificially-structured "wave-function-engineered" semiconductors, focusing on epitaxial compound-semiconductor compounds and alloys. The relationships among electronic, optical, and transport properties are emphasized, as are the implications for design and performance. Materials of particular interest include the familiar III-V compounds and alloys; newer offspring of these, such as the dilute-nitride III-Vs; ZnO and II-IV semiconductors; and spintronic materials. Exploratory studies of less commonly studied materials which may be of increasing future interest are also featured. Topics include: low-bandgap and dilute-nitride semiconductors; growth, structure and defects; emitters, detectors and solar cells; devices; zinc oxide; spintronics and quantum structures; quantum dots and wires-structure, spectroscopy and transport; and quantum dots and wires-devices.
