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

Symposium V, "Rare-Earth Doping of Advanced Materials for Photonic Applications," took place during the 2011 Spring Meeting of the Materials Research Society in San Francisco, California, April 25−29, 2011. It brought together researchers from a number of fields that traditionally do not interact closely with each other and provided the semiconductor, phosphors and device communities with a unique opportunity to discuss fundamental topics of common interest that underlie the emission in rare-earth-doped materials. Such a mix of different research topics, silicon photonics, phosphors, oxides, and wide band gap materials including III-nitride semiconductors, to name a few, greatly promotes a healthy and vigorous exchange of ideas. The goal of this symposium was to highlight the status of light emission at infrared and visible wavelengths from rare-earth-doped phosphors as well as semiconductors. Issues of rare-earth-materials applications for green technologies, sustainability and opportunities for development of multifunctional devices utilizing magnetic, electric and pressure stimuli were also addressed.

Recently, the preparation and characterization of materials in the nanometer scale has become challenging in the field of material science. Materials in the micrometer scale mostly exhibit physical properties as same as that of bulk form; however materials in the nanometer scale may exhibit physical properties distinctively different from that of bulk. Semiconducting nanoparticles have attracted widespread attention because of their special optical and electronic properties arising from the quantum confinement of electrons and large surface area. Among the semiconductor materials, Zinc Sulphide (ZnS), shows various luminescence properties such as photoluminescence, electroluminescence and thermoluminescence. Hence, ZnS is a traditional phosphor widely used in flat-panel display, electroluminescence devices, infrared windows, sensors and lasers. When ZnS material is doped with transition or rare earth metal ions, it is possible to modify its physical properties. For doped nanocrstalline semiconductor materials, quantum confinement effects in the energy states also produce unusual optical behaviour. In this book, undoped and some transition metal ions doped ZnS semiconducting nanomaterials were synthesized by microwave-assisted solvothermal method. To prepare the undoped ZnS nanoparticles, zinc acetate and thiourea were used as the precursor materials and ethylene glycol was used as the solvent. The solvothermal method used in this present work is an effective method for preparing metal sulfides under mild conditions, which is a simple, cheaper and convenient method. ZnS materials doped with transition metal ions were also synthesized by the same method. In the present work, ZnS material was doped with manganese, copper, cobalt and indium in four different concentrations. The microwave treated precursor materials, after washing with de-ionised water and acetone and after annealing leads to fine nanocrystalline powder.
