Book Description
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

Book Description
Modern techniques to produce nanoparticles, nanomaterials, and nanocomposites are based on approaches that frequently involve high costs, inefficiencies, and negative environmental impacts. As such, there has been a real drive to develop and apply approaches that are more efficient and benign. The Handbook of Greener Synthesis of Nanomaterials and Compounds provides a comprehensive review of developments in this field, combining foundational green and nano-chemistry with the key information researchers need to assess, select and apply the most appropriate green synthesis approaches to their own work. Volume 2: Synthesis at the Macroscale and Nanoscale explores synthesis at different scales. Beginning with a selection of chapters discussing a range of macroscale topics, the book goes on to explore such important areas as metal nanoparticle synthesis, biogenic synthesis, and synthesis of enzymes. Further chapters explore the role of Metal Organic Frameworks in greener synthesis, synthesis from renewable sources, and impacts of nanomaterials synthesized by greener methods. Discusses the synthesis of widely different groups of chemical compounds and distinct materials Reviews synthesis at both the macro and nanoscales, including information on metal-organic frameworks, carbon dots and ionic liquids Provides examples of applications to support learning and guide implementation of theory in practice

Book Description
This book discusses the theory of the electron states of transition metal impurities in semiconductors in connection with the general theory of isoelectronic impurities. It contains brief descriptions of the experimental data available for transition metal impurities belonging to iron, palladium and platinum groups and for rare-earth impurities in elemental semiconductors (III-IV, II-VI and IV-VI compounds) and in several oxide compounds (TiO2, BaTiO3, SrTiO3). Also included are applications of the theory to the optical, electrical and resonance properties of semiconductors doped by the transition metal impurities.The book presents a theory unifying previously proposed ligand-field and band descriptions of transition metal impurities. It describes the theory in the context of the general theory of neutral impurities in semiconductors and demonstrates the capabilities of this description to explain the basic experimental properties of semiconductors doped by transition metal impurities. A detailed discussion of various experimental results and their theoretical interpretation is carried out.This book comprises three parts. The first two parts consider several exactly solvable models and describe numerical techniques. All the models and simulations constitute a general pattern describing transition metal and rare-earth impurities in semiconductors. The final part uses this theory in order to address various experimentally observed properties of these systems.
